As an FYI, if you want to buy a SIM, buy it soon... I emailed straight talk about why I was charged $15 for the MicroSIM, when it's always been advertised as $7, and their reply was "prices online are subject to change without notice." So, be forewarned, it may not always be $7.. Grrrr.......

Verizon S4 4g LTE?

I was looking to get a verizon S4, and just putting in a new straight talk ATT 4g LTE sim, but I'm not sure if the LTE will work with the Verizon version of the phone. And if LTE doesn't work, would 3g still work?
[AT&T Samsung Galaxy S 4 General] iviyth0s:
I think LTE is a national if not world standard so it should work fine.

MMS issues only for locked phones???

I've been chasing this MMS issue with my S4 Active SGH-i537 since I switched to Straight Talk last month. Phone calls, SMS, and all other data are perfect. I've tried every APN setting I can find. I bought the phone off Craigslist, and it was previously on AT&T. I am using the AT&T network with Straight Talk.

As best as I can tell, this phone is locked. (One test seems to be *#2263#. If it goes into Service Mode then it is unlocked; if it gives a RAT Selection option is restricted message, then it is locked.)

Perhaps this is obvious to everyone else, but is the common thread to success versus failure for MMS network locking? That is, are unlocked phones consistently able to use MMS (with the right APN, of course) and locked phones consistently unable to use MMS, despite the APN settings?

If so, then I know where to focus my energy. This might also be a good notice to those who, like me, are looking to buy a phone for the BYOD plan.
[AT&T Samsung Galaxy S 4 General] maddawg138:
Doing that on my phone states that RAT is restricted but I have no problems with MMS... I use the ATT straight talk sim.... When I bought it.... it was suppose to be unlocked...
[AT&T Samsung Galaxy S 4 General] Androidjr:
I have a Galaxy S4 under contract with Verizon. I'm thinking about paying it off and switching to StraightTalk.

Do i need a specific Sim for Verizon Phones or can i use the AT&T SIM?

any other suggestions are welcome.

TIA

**EDIT**

Do i need this ebay.(DOT)/itm/STRAIGHT-TALK-CDMA-ACCESS-CODE-KIT-VERIZON-3G-SPRINT-3G-4G-NETWORK-/331102750627?
[AT&T Samsung Galaxy S 4 General] somoose:
Thanks maddawg - this helps. So I'm wrong about the association with RAT restriction, but so far that doesn't change my theory on whether the phone has to be unlocked. I've asked the previous owner of my phone to request that it be unlocked from AT&T, and I expect that he'll hear back from them in a couple of days. We'll see if my theory is true.

For the record, AT&T has a website to request unlocking of their phones by former customers. If I read it properly, AT&T will unlock a phone if all early termination fees have been paid.

---------- Post added at 03:32 PM ---------- Previous post was at 03:26 PM ----------

Verizon phones do not use SIM cards and are not compatible with AT&T. However, I believe Straight Talk also resells service on the Verizon network, so it is still an option. You will need to pay off your early termination fee so you have a clean ESN in order to transfer that phone to Straight Talk.

Yes, you will still need a kit like that, but I would buy it either at WalMart or directly off the Straight Talk website. The price is roughly the same, and there's no need to gamble with ebay in this case.

I have a SGH-I337 on straight talk. I got the "download" issue with mine ever since I got it(bought it brand new unlocked). I can call, use internet, send and receive sms messages, send mms message, but upon receiving the mms message it gives me that 32KB message that wants me to download and it tries and fails. I have tried so many different APN settings, countless calls with straight talk (they say it is my device), I called the company I bought the phone from and they said it is an APN setting, they had me hard reset the phone twice (didn't fix it). I have been going crazy with this for a few weeks now. I have tried download messaging apps and they don't fix it. Someone please help!
[AT&T Samsung Galaxy S 4 General] muniz_ri:
Go into settings/more networks/mobile networks and make sure mobile data is checked and stays checked after reboot. May or may not be the issue but worth a shot.
[AT&T Samsung Galaxy S 4 General] mattgyver:
Are you using the stock messaging app, or something like [8SMS/Handcent/Google Hangouts] to send and receive mms?
[AT&T Samsung Galaxy S 4 General] Croaky:
I have made sure my airplane mode is off and my mobile data is checked. They are both correct. (my wifi is off as well)

I am using stock messaging. I have tried a bunch of other app messaging but none of them fixed the issue.

Could there be any stock security filters that could be causing this issue? I am unsure how to check them. AT&T really overloads these phones with so much junk.
[AT&T Samsung Galaxy S 4 General] mattgyver:
What are your current apn settings? Also, straight talk always makes it a point to say they don't guarantee mms....

[AT&T Samsung Galaxy S 4 General] Croaky:
Prior to having this SGH-i337 phone, I had a straight talk S3 - no sim (using the same service plan, i bought a 1 year plan) and everything worked on that one. I bought this SGH-i337 end of December 2013 brand new and it had this problem from day 1. I had to purchase a gsm sim and switch my plan/number over to the sim to use this new phone.

I got a different story from each straight talk employee I talked to. "We don't guarantee mms will work" "Your phone is not fully unlocked" "There is a problem with your phone please contact samsung" "It is not a problem on our end"
[AT&T Samsung Galaxy S 4 General] iviyth0s:
So when did you do the switch, Jan 1st??
[AT&T Samsung Galaxy S 4 General] Croaky:
Yep it was around Jan 2 or so that I did the switch. They had a lot of problems doing the switch because my 1 year plan wasn't showing correctly in their system so they had to do a manual port in after 3 phone calls with them. Then my sim has been screwed up ever since and they keep sending me new ones to fix the problem (problem is it is a different phone number showing on my sim online, but my actual phone number and everything actually work correctly in the phone). They can't fix it through a new sim each time but they keep sending me new ones to try. I asked them if that could be causing the problem with the MMS issue but only one guy said yes, the rest of them said no.
[AT&T Samsung Galaxy S 4 General] iviyth0s:
So everything's completely stock rom and everything?
[AT&T Samsung Galaxy S 4 General] Croaky:
Everything is stock. Was unlocked brand new. I did a hard reset twice and it didn't fix it.

Can everyone using a SGH-i337 on straight talk post their APN settings. I tried so many settings already but I'd like to try more of the phone specific ones, hopefully there is just a different setting that this phone requires.

Verizon Galaxy S4 on Straight talk?

So you are saying that I can buy a verizon glaxy s4 from someone and take my att compatiable straight talk micro sim card and put it in the verizon galaxy s4 and it will automatically work? Or are there other steps I need to do for it to work? Also will the phone be using AT&T's towers since its an AT&T sim card? If there are other steps please explain to me how to do it! I don;t want to buy the verizon galaxy s4 from someone and it not work. Also will I get 3G or 4G LTE? I hope for at least 3G!

What a relief. After nearly a month of calls to Straight Talk and them sending me about 4 different "new" sim cards, I finally received one that worked. My phone number if finally showing up correctly on my online account and my MMS actually works now! Now to get them to fix my end date since that is now showing incorrectly. For anyone else having a problem with their MMS.. check your online account and see if it shows your actual phone number attached to your sim. I am using ST's recommended APN settings as well.

To all ..To avoid any confusion. When asking walmart about the kit..Ask for the "Bring your own phone" straight talk kit. I bought cash price att s4. The kit has 4 simple sizes. IPhone micro standard and all you will need. I have heard lte is a hit and miss. But just get connected. Then go online to the straight talk byop plan. Go to Apn. It will ask device and brand. Carrier etc. Then go into your settings in network. Type it in. Your good to go. It worked for me. I get 2.5 gig lte for 45 a month. Unlimited everything. But 3g after 2.5 gigs. But me being the phone nerd I am I'm testing the cap now. I'm at 4 gig lte. When I know this works a little bit more. I'll share my progress. Peace.

you can use any verizon 4g lte phone on straight talk. i have a s4 active from att that i use on straight talk and my buddy has a verizon s4 i took my straight talk sim card and put it in his phone and it worked he didnt have 4g but that was because of the apn settings but he was able to make phone calls and send messages and have hpsa+ for data. i just had to go into the network settings and switch it to gsm and manually change the network provider and change the apn setting to straight talk even after all of that tho it still said in the upper left corner that the sim was invalid but at the same time it did recognize phone number that was on the sim i believe that this was because it was an att straight talk sim ( which they do still sell in the straight talk sim start up kit) so yes you can use any verizon 4g lte phone on straight talk even when straight talk says the phone is not able to you may have to activate the sim in a different phone first but it will still work in the verizon phone have you can some setting but you might have to deal with it saying invalid sim
