[T-Mobile myTouch 4G Slide] tmittelstaedt:
I just thought I would relate my newbie story on this for any other newbies.

My son bought a TMobile 4G Slide from Ebay a few months ago for $50 and used it on TMobile Prepay no problem, then wanted to move it to Consumer Cellular (he's a low volume user so their plans would be a much better deal for him)

So he asked me to move the phone. I did make him root it for the experience but since the financial stuff required credit cards and he's only 16 I took care of the accounting stuff.

So first thing was ordering the SIM card from CC. That came the next week and I plugged it into his phone. No dice, the phone wanted a network unlock code. I expected that but just wanted to check.

So I called TMobile for the unlock code. Got transferred to pre pay tech support. Ok no problem. Pre Pay TMobile tech support says 'we won't unlock it because there's an amount owing, call our contracts dept."

After wasting an hour or so getting transferred around it finally dawned on me the issue - TMobile has separate tech support departments for Prepay and Postpay accounts. Because this phone had been originally bought on a Postpay account, the Prepay support people couldn't lookup **** on the IMEI number. So I call back in and this time ask for a representative and asked to get transferred to postpay customer service.

I finally get a knowledgeable rep. from Postpay who can look up the IMEI number. He tells me "the IMEI on this one is perfectly clean, there's no outstanding insurance claims or unpaid bills" So much for the dingbats in the other support group.

But, there's a problem. The rep explains that the only way to request a network unlock code on a TMobile phone is to call in, identify yourself as the contract holder (with the phone number of the account, and the PIN) for the matching account that was last used on the phone. If the phone was sold as prepay then you have to call in as the last prepay telephone number to come up on the phone, if the phone was originally sold as post pay you have to call in as a post pay account holder for the account the phone's IMEI was last used on. He said go back to the guy you bought the phone from and ask them to network unlock it.

So I'm stuck. So I dig around in my junk box and come up with an older TMobile 3G slide. This is the predecessor to the 4G slide, it was made by HTC and was used on my wife's TMobile post pay account (which is still active) until she upgraded. So I call into TMobile with that phone, give them the IMEI and a few days later I get an email from TMobile with a network unlock code for the 3G.

I stick in the Consumer Cellular SIM to the 3G and it comes up. But, it cannot get on the CC data network. Voice and text work fine, data does not. I call CC's tech support and they try a bunch of different things, nothing works. They say "well sorry you will just have to upgrade your phone"

So now I'm back to the 4G Slide. So I start searching the Internet can come up with http://unlockcode247.com/ They want $4 to unlock the phone, I figure what the hell. I send them the IMEI and the money and a few hours later I get an unlock code.

The code works, the phone gets on the CC network, and now both voice and data are working just fine.
