I called the AT&T management team, reached an engineer, didn't ask for supervisor, however the woman who answered was very helpful. I told her this was part of a trend. Anyway, she told me to go to best buy and have them do a smartflash. She also said to make sure my pictures and contacts were saved. I went to best buy - they had me talk to in house Samsung rep. He did the smartflash, took less than 15 minutes. - no cost. This was done tuesday afternoon, so far no lost connectivity. It's been over 24 hrs. Before I would lose connectivity at least 10-15x a day.

This has seemed to work so far for me.

I purchased the microcell, but was given the same amount of credit on my at&t bill.
[AT&T Samsung Galaxy S6] redeyss:
Please keep us posted if the issue does or does not return. Thanks!
[AT&T Samsung Galaxy S6] GeorgeP:
I was having an issue with calls disconnecting. I called ATT, and rep suggested I disable auto handout. I did that and have not had a call disconnected in about 5 days. The downside to the change as I understand is that if I leave the range of the microcell while on a call, the call will disconnect. I can live with that.
[AT&T Samsung Galaxy S6] Globalrebel:
I have this same issue, and wonder what the SmartFlash does? Can anyone speculate or inform us on what this actually is? I don't want to start over from scratch again :)

I'll be calling in to the number provided tomorrow and will report back. I also paid for mine (the new small black one) but received the credit back on my account.
[AT&T Samsung Galaxy S6] asdfdemi:
I am not sure what the SmartFlash is, so I'll try hitting up a Best Buy as soon as I can to check out what that is.

I have tried disabling the auto handout, but my phone still gets the dropping signal. Unfortunately I still have no fix here, so I'll try what I can and just pray that something turns up so I can post a resolution here.
[AT&T Samsung Galaxy S6] jonrobertd:
26 hour old S6 Active here, yeah, dropping all the time. Even taking minutes to dial out, and having issues with texts not sending.
[AT&T Samsung Galaxy S6] hgtuch50:
If you mean you only have phone for 26 hrs - get rid of it and trade it in for s5 or anything else. If you go beyond 14 days - they call it past buyers remorse period. I didn't realize what was happening until 6 weeks out and they would not let me trade it for something else. Told them not buyers' remorse, just that phone doesn't work. They didn't care.
[AT&T Samsung Galaxy S6] johnleeaddison:
Not the only one

Glad I'm not the only one. Went post my 14 day period with the S6 Active. Constantly having to toggle airplane mode on and off to reconnect when I can't place calls or send text messages.
[AT&T Samsung Galaxy S6] hgtuch50:
I tried to toggle airplane mode on and off and did not reconnect for me.

Just to let everyone know --- the smartflash did not work. Still intermittent. Then they had me take off the enhanced 4G LTE services - didn't work either. When I spoke to them today, they said there is nothing else they can do for me, their production people are working on it. Could take weeks or months, but not years. So I have to have this phone with intermittent service in my home and if I have an emergency phone call to make and phone not working oh well, too bad.

I sent in a formal consumer complaint today to the consumer affairs for the state of Florida. I will see what happens with that.

Good luck to us. HA HA
[AT&T Samsung Galaxy S6] redeyss:
Look into Google voice and Google dialer and hangouts. You can make WiFi calls using those apps, could be a workaround for now.
[AT&T Samsung Galaxy S6] Globalrebel:
Update being pushed today by AT&T. Hoipefully this will resolve issues with cell tower. I will not take update as I have my phone setup just the way I want it. Waiting for 5.1.1 before doing that. Can someone else test update and report back on cell tower issues?
[AT&T Samsung Galaxy S6] dandrumheller:
Beware of the update - probably will patch the exploit used by pingpong. Have not seen confirmation either way yet.
[AT&T Samsung Galaxy S6] redeyss:
Thought we weren't rooted yet?

I took the update and re-added my number to microcell, then made about 6 minute call without dropping. Will make some calls tomorrow and report back, crossing fingers.
[AT&T Samsung Galaxy S6] dandrumheller:
Huh? AT&T S6/edge has had root for quite some time. S6 active does not.

Sounds promising about the microcell behavior though, so that's cool.
[AT&T Samsung Galaxy S6] redeyss:
Yeah whoops, forgot there isn't an s6 active forum yet and I'm in the s6 forum with s6a.

Realty hope this MC thing has been fixed too.
[AT&T Samsung Galaxy S6] Globalrebel:
All new roms are unable to be rooted until Ping-Pong add's the ability for them to be rooted (if the exploit still exists). I'm waiting regardless to make sure its even worth it. My phone has been working fine, except for the damn MC issue, so no reason to update unless its worth it.

On a side note, I'm happy knowing android M will be brought to the S6!!

S6 Gets Android M
[AT&T Samsung Galaxy S6] hgtuch50:
I received an email today from someone who works in the office of the President of AT&T. This was probably based on my consumer complaint to the state of Florida consumer affairs.

Of course I tried calling him twice, but call did not go thru - not enough bars on the phone now - only 2 .

Will try again later and let everyone know what the outcome is.
[AT&T Samsung Galaxy S6] Globalrebel:
Any update on this? I'm starting to get pissed and need to have a phone that will work at home!
[AT&T Samsung Galaxy S6] dandrumheller:
FYI post here: I updated to the OF3 build via Designgears flashfire/Odin process, so I'm running the new modem, kernels and firmware with old bootloader and recovery. The new radio does NOT want to stay connected to my microcell. It will connect momentarily, then drop the connection almost immediately. My wife is having none of those issues on her non-rooted ota updated edge.

I don't believe anything in Designgears process caused this - but haven't been able to solve it yet.

Edit : a power cycle of the microcell seems to have significantly improved matters for me. Will continue to monitor, but after cycling last night, it appears to be behaving normally.
[AT&T Samsung Galaxy S6] redeyss:
I took the update on s6 active and had no dropped calls on my microcell afterwards. That doesn't mean that much because sometimes I could make a 5+ minute call without drop and other times call would drop within 30 seconds (pre-update). Soooo, promising but inconclusive here.
[AT&T Samsung Galaxy S6] hgtuch50:
I heard from the office of the President of AT&T. He said he is looking into what he can do to resolve my problem.

I told him a new S6 would not solve the problem with the microcell. He said he would look into what the company can do to get a new S5 for me, which seems to work with the microcell. I don't know if S5 & S6 is the same size, but if I downgrade to S5, I would also need new screen protector and cover for the phone, if not the same size.

He said he would notify me by 07/17/15. I'll let you know what happens.
[AT&T Samsung Galaxy S6] redeyss:
You would do better to sell your s6 and buy an s5 for $300 or less. The s6 is worth $500 or so I would think. At least make them give you a Lg g4 or HTC m9, flagships that are comparable to your phone. My Lg g4 works with the microcell flawlessly, fyi.
[AT&T Samsung Galaxy S6] glued916:
I have had the same issue. I bought the Samsung s6 edge and i thought it was defective. I got ATT to send me a new one and in the meantime i bought a Samsung S6 Active and i had the same issue. My wife has an iPhone 6 and she did not have issues. I thought it may be that my microcell was 5 years old so i bought a new microcell today and i still have the same issue. There is definetly something going on with the Samsung S6 on ATT...
[AT&T Samsung Galaxy S6] asdfdemi:
Unfortunately I have no new updates on this matter. I am still having all the same issues and AT&T still has not given me any updates on the trend. Honestly, I don't think that we'll see any fixes anytime soon, if at all. I cannot say anything with great certainty, but given the timeline of this issue, it seems as though we will just be at the liberty of Samsung to give us an update that fixes any Microcell issues.
[AT&T Samsung Galaxy S6] horsing.around***:
I am not a developer - just someone who switched up from a Galaxy S3 to an S6 and had problems with my Microcell. My husband made the same switch and had the same problems. We encountered having full lines that would drop to nothing when a call was initiated, having to then search for the MC and immediately make the call. Incoming calls were going directly to VM instead of ringing through.

I have been participating in a thread in the AT&T community and contacting AT&T.

This is my most recent posting - maybe some light at the end of the tunnel until there is a permanent fix:

**********

As indicated in a prior post last week she said via her end she undid HD voice and then I unregistered and re-registered the microcell. Things were working good then it reverted.

Like a person with a sore spot I checked again for others with the problem hoping something new cropped up. Found a post the referred to the HD voice and it explained how to locate it in settings. Settings>Connections>Mobile Networks>Mobile Data>Enhanced 4G LTE services.

When I checked my setting the box was checked. Hmm - worth a try. I unchecked the box. Ever since I have not had any problems sending or receiving calls. Never once has a call gone to VM instead of ringing. My lines no longer drop from full to nothing when I initiate a call.

My husband, with the same phone, was still having problems. I purposely did nothing to his phone so I would have the comparison. Hmmm - so I went into his settings and uncheck. Now he too is not having any problems.

I still cannot sent text messages with images while in the range of the MC but that is a separate issue to deal with.

*****

I wanted to share this because I found this thread helpful when first researching.

Thanks
[AT&T Samsung Galaxy S6] asdfdemi:
While I wish this were a viable fix for me, it was one of the first things I had tried. I'm still having this issue, and I haven't been any closer to a breakthrough in a while. I'm just hoping something pops up that'll fix Microcell issues with newer phones.
[AT&T Samsung Galaxy S6] kuaka:
This is still my problem. Called in and talked to a very helpful tech at AT&T who is forwarding this problem to an Engineering team that deals with the Microcell.
[AT&T Samsung Galaxy S6] sirooga:
I finally gave up and unplugged my microcell.
[AT&T Samsung Galaxy S6] redeyss:
I went into hidden menu by dialing *#*#4636#*#* and setting network to "GSM only" instead of "LTE, gsm, auto" It uses 2g instead of 3g so I can keep microcell running.

The dropped calls are random, made three calls on MC this afternoon and didn't drop. Who knows.!?

From my s6 active.
[AT&T Samsung Galaxy S6] DDMan:
Just got off the phone and got my own case number and had it attached to the parent case here. Galaxy S6 Active with all the same problems. I have no cell signal at my house, but the microcell has worked great with my Captivate and my GS3, along with 3 iphones. I have pics of it taking over an hour to send a pic message, and 7 texts all coming in at once.

They're well aware of it. Just a heads up, the case team is supposedly changing phone numbers. Their new number is:

1-866-986-0965
[AT&T Samsung Galaxy S6] asdfdemi:
Thank you. I'll update the phone number in the original post.
[AT&T Samsung Galaxy S6] CL3P20:
<- Former Cellular tech

*Without seeing logs or being able to do isolation testing: This sounds like standard interference coming from Tx power levels being too high.

RSSI levels should be monitored on the device to see if your Rx level is degrading from 'cascaded' Tx power levels. GSM working with no disconnect is further support from this theory.

LTE is highly sensitive due to its speed. Your other devices, likely did not Tx as high or as 'fast' as the G6.. which means your MC power levels need to be lowered. An alternative solution would be to add 1.5db attenuator to the coax feed between antenna and MC. This additional attenuation will 'knock down' the incoming interference level seen on the Rx side, by reducing effective output of the MC Tx power.

You can purchase an attenuator at any electronic store.. You need a 1.5db RF attenuator good for ~5W of power. I would be very surprised if this doesnt clear your issue straight away. Either way its much cheaper and easier than replacing phones/MC. Just power the unit down, disconnect the RF line - add att. - reconnect RF and restore power. Couple minutes to sync and you can test.

*The idiots your dealing with at ATT.. well.. they are just that. They could barely keep their own network running... which is why I was so busy for the 15yrs I spent handling issues like this in the field for them and other carriers. :p

**and if your data for MMS isnt working though your MC - COMPLAIN ! Get those derps to do their job and correct the routing mistakes in their damn scripts! Its a simple fix.. and your paying customer. Let them know VZN rep told you that with their MC you wouldnt have this problem !! Lolz.
[AT&T Samsung Galaxy S6] redeyss:
So add the attenuator anywhere along the coax before cable modem? Will it kill speed and signal strength?

From my s6 active.
[AT&T Samsung Galaxy S6] fakeasdf:
I jumped on the bandwagon, I was told they'd add me to the parent ticket.
[AT&T Samsung Galaxy S6] fakeasdf:
That unfortunate that people are still experiencing issues, mine seemed to be resolved as of a week or so ago, but it's probably more likely I haven't been paying attention.
[AT&T Samsung Galaxy S6] redeyss:
I had to exchange my s6a with at&t because of this issue. I would like to pick the active back up when the microcell issue is resolved. Using a G4 now but I would go back.
[AT&T Samsung Galaxy S6] redeyss:
Anybody with an s6 and microcell confirm the 5.1.1 update fixed the issue?
[AT&T Samsung Galaxy S6] sirooga:
Just plugged mine back in. I'll test it out over the next few days and see if anything has changed.
[AT&T Samsung Galaxy S6] redeyss:
Thanks! I'll be shocked if they didn't fix this since it's been a known issue for so many months.
[AT&T Samsung Galaxy S6] sirooga:
Doesn't seem to have fixed it for me. Still randomly not connected to microcell. There is a search for microcell option in network operators menu. Not sure if it was there before.
[AT&T Samsung Galaxy S6] fakeasdf:
I'm still on 5.0.2 and it has been significantly better, though I'm curious if it's because I've had wireless off. Im still on the unlimited plan, so jumping to wireless doesn't matter to me. Just my current theory since I doubt they fixed anything...
[AT&T Samsung Galaxy S6] CL3P20:
Correct. Place the attenuation anywhere between the MC and the antenna. This should be a larger coax connection, like FJ4 and not the small stuff your TV is on (RG type).

*knocking down the Tx power a bit with additional attenuation will at least let you know if the MC is causing its own issue, by creating a feedback loop due to the Tx power being too high. If the issue remains with no change - you can be confident that the issue is in the routing & scripts which connect the MC to ATT's network... only they can correct that.
[AT&T Samsung Galaxy S6] angel wen:
Hi, do you have any undated news from your case? I have a same issue with my s6 edge.
[AT&T Samsung Galaxy S6] sirooga:
Still broken.
[AT&T Samsung Galaxy S6] xmayhemreturnsx:
I had the same exact mms issue on a T-Mobile galaxy s6 edge. After experimenting with some settings I determined it had to be something wrong with the apn. I check the apn setting and I saw that the s6 defaults to apn ipv6 protocol. So what I did was create a new apn and set everything to the same except for the apn protocol that I set ipv4 and lo and behold my mms were sending without me having to reboot the device. This may resolve your micro cell issue maybe you could give it a try.
[AT&T Samsung Galaxy S6] BeastLogic:
Any one have any updates on this issue?
[AT&T Samsung Galaxy S6] mrbogusbaxter:
Here is what worked for me and quite a few in my office (Tested on Galaxy S6 Edge + and GNote 5).

The fix for Microcell & MMS. It took me ages to figure this one out. ATT did not help what so ever.

Good Luck.

** Important to follow this specific order.

Power Down Router for at least 2 minutes.

Power Down Microcell for at least 2 minutes.

Go Into Phone Settings:

UNCHECK Enhanced 4G LTE Services (2x)

Settings >> Connections >> Mobile Networks >> Mobile Data >>

Settings >> Connections >> Mobile Networks >> International Data Roaming >>

* Reboot phone

* Power Up Router.

* Power Up Microcell.
[AT&T Samsung Galaxy S6] bigwillyg:
do you still have the enhanced lte services unchecked or no? My wife is having this issue with our microcell and its driving me nuts because nothing I do fixes it.
[AT&T Samsung Galaxy S6] unobtrusivetones:
Microcell finally working on Note 5

I've been having the same issue connecting to my Microcell with my new Note 5 and here's what happened.

I recently upgraded to a Note 5 through the AT&T website and received the new phone and decided to pop the SIM card from my Nexus 6 (Which was previously connected to Microcell). I went through the setup of the Note 5 and the Microcell would never connect no matter what I did. I reset and rebooted my router and modem, de-activated and re-activated the Microcell and still nothing. Finally, After a few weeks of struggling I decided to go to AT&T and get a new SIM card as a last resort however, the rep looked at my account and noticed I didn't accept the "terms and agreement" on the new phone so the phone was never actually tied to my account. He accepted the new terms for me on my account and got a new SIM card and as soon as I walked through the door at home BAM! My Note 5 connected immediately to the Microcell.

The funny thing is there were no instructions in the box for accepting the terms and agreement on the new phone so make sure you guys get a hold of AT&T if you've recently upgraded your phone and can't connect to your Microcell .

Dumb User

I am just a "Dumb" User. I find this post incredibly useful and have experienced all the problems mentioned - have replaced, equipment, etc., etc., and I am dumbfounded that ATT can say "we don't guarantee the equipment we sell will work in all environments" - that is absurd given that Cisco makes the microcell and Samsung makes the phone. Thank you again for your post and the information. Miles

---------- Post added at 06:11 PM ---------- Previous post was at 06:07 PM ----------

Yes, and the problems got worse with 5.1.1. My Nexus 5 with Marshmallow works great.
[AT&T Samsung Galaxy S6] sentinel_cm:
Just checking back to see if anyone else has made any progress. I can say that turning OFF the Enhanced 4G LTE Services did NOT solve my problems. I have reached out to Samsung in a desperate attempt to get this fixed. I now have 2 S6 Actives, BOTH with all of the problems everyone else describes when at home on my MicroCell. 4 other phones prior to these were fine on the MicroCell. Text are BAD, but sending a picture (925kbs or so) is almost impossible. I have found that smaller sized pics will send much more reliably than the size I normally take them in (does anyone shoot low res?.... prob not).

Chris
[AT&T Samsung Galaxy S6] CFoote:
This is hugely disappointing, I still have an old S3 I use daily and wanted to upgrade to the S6 Active for the great battery life, but if Samsung has no desire to resolve this, I'll wait for the S7 or simply forget Samsung all together. How can no one at ATT move this up the chain and get Samsung on the phone to move things forward. sigh.

Chris
[AT&T Samsung Galaxy S6] splash5:
anyone know if the new 5.1.1 update helps at all?
[AT&T Samsung Galaxy S6] redeyss:
Bump, looking to pick this phone up again but only if the microcell issue has been resolved.
[AT&T Samsung Galaxy S6] splash5:
i can't say for sure but i added mine back to the micro cell and it has behaved for 24hrs (it was unusable for me in the past), i will test for a week and report back.
[AT&T Samsung Galaxy S6] redeyss:
How's it going with the microcell?
[AT&T Samsung Galaxy S6] splash5:
It works !!!

For the 1st time since i got my s6active i can make calls at home, and it works when i leave the house... its almost as if i have a really cell phone agin. shame i still had to by a microcell to make my cell service work in my area, but at least i can make and receive call, text and MMS again.
[AT&T Samsung Galaxy S6] redeyss:
Thanks for the reply! Bring me up to speed, did it get 5.1.1 update and began to work with MC after that?
[AT&T Samsung Galaxy S6] CFoote:
Yes, please update us on what has happened...the S6 Active is a great phone, if the 5.1.1. update made it work with a microcell that is fantastic.
[AT&T Samsung Galaxy S6] splash5:
yes the 5.1.1 update was the only change, i had tried two s6 actives and they were both unusable on the microcell, the day after 5.1.1 update i figured id try again now the the past week and a half I've had no problems.
[AT&T Samsung Galaxy S6] CFoote:
Fantastic. Can anyone else confirm the 5.1.1 update now works OK with their microcell?
[AT&T Samsung Galaxy S6] sentinel_cm:
I can confirm beyond a shadow of a doubt that the 5.1.1 update does NOT help the situation with the MicroCell.

I have 2 S6 actives, one with the update, one without. Both SUCK when it comes to reliable use with my MicroCell. Texts are bad, picture messages are worse (if not impossible most times). Receiving or making a call while on the MicroCell is hit or miss, about 50/50.

Biggest problem is I NEEDED my phone this morning for a medical issue and could not make the call to save my life. Thankfully the situation was not dire and all is well now. But the entire reason I have the MicroCell is because I get poor reception at my home and my cell is my only phone. It's a problem! and now I have the rest of the day off and can play phone tag with support.... fun fun.

I will post an update if I get anywhere with them.... doubtful.

Chris
[AT&T Samsung Galaxy S6] sentinel_cm:
I called ATT again today and spent an hour and a half on the phone with advanced support. To make a long story short he basically dissociated my MicroCell from my account and re-added it. The purpose of this was to cause the MicroCell to reach out to Cisco and download the most recent software update. The update does not occur with a reboot, or any other way (dumb).

I was told to try it for a day and he would call me back tomorrow afternoon. Initial testing results are encouraging, I made over a dozen calls and had 3 calls come in with no issue. Normal texting is currently working OK, but picture messages remain an issue. According to advanced support.... even though you are connected to the MicorCell it still tries to send pictures (and texts) over the cell data to the nearest tower and NOT through the MicroCell.

However they can't explain why I never had this problem with my MotoX, HTC Vivid, Galaxy S4, or Galaxy Alpha. He is going to talk to his manager and see if they will replace the MicroCell with the newer black model, I have the white one.

All in all it was a good call, the tech provided very good support and was very personable. And I at least have some hope there is a light at the end of the tunnel.

Chris
[AT&T Samsung Galaxy S6] redeyss:
I never had problems with mms but will also get a couple bars of H+ when not in microcell. My problem was random call drops, sometimes within minutes, sometimes could go 30-40 minutes on a call on MC.

Keep us posted! Thanks
