    Hi. I've recently purchased a Verizon S3 from a private owner who assured me that the phone was fully functioning on T-Mobile. I can make and recieve calls on the phone but I can't recieve mms or browse the web without wifi. I have superuser and believe the phone is rooted. Please help

    The way i have found to get data working is use apn manager and add the apns for t mobile in your phone there are lots of videos about it on youtube

    I have recently switched my Verizon Samsung s3 to a t-mobile network. The phone is unlocked and i can make calls and text but Verizon has disabled the ability to change apn numbers on this phone. Is there anything I can do?
    Thanks!

    Not really sure but the Sim card for Verizon is for LTE only and not GSM. The Titanium backup suggested by Stephen is for Rooted phones only. The only way you may get it working is to Root, but no guarantee.

    I had the same exact problem. My phone is not even rooted but unlocked! At least when I run Titanium on it, it said that it has not rooted! But I just went to setting>>more settings>>mobile networks>>Access point Names>>press menu button>>Add a new Access point
    Enter Data as:
    APN settings for data and picture messaging (MM... | T-Mobile Support
    Be sure your setting is Global and Roaming is active (You can deactivate Roaming later)
    Hope it help you

    It may only work on 2G witch is slow enough for the MMS and web browsing to time out. I don't know of any way myself.

    [MOD] Add APN editor to System Settings

    Try this if you have not found any other solutions. It worked for me.

    Am thinking about switching carrier from Verizon to Tmobile & have G S3. It is a SCH-I535. The Tmobile website states all I need is their sim card but this forum states otherwise? Has anything changed recently?? (phone is not unlocked & not rooted)

    I got the data and mms working today on the Verizon S3 for Tmobile. As stated, it is only 2G Edge speeds. All I did was add the Tmobile APN settings, in Global mode. No issues after that. Didn't even have to reboot. After I entered the apn settings, and chose Tmobile in the apn list, the E symbol came right on. Hope this helps people.

    Was your phone LTE capable? I have the same phone and have heard the LTE phones won't work. I am not concerned about getting fast internet as I am near wifi 98 percent of the time, but want to make sure calling/texting will work. Thinking about Net10 AT&T SIM BYOP plan. Thanks!

    It really should be the APN settings, I was in Mexico and popped a telcel card in my phone (Verizon Note 2) and it would not get internet until I changed the APN settings. My phone was rooted though.

    T-Mobile uses a different frequency for it's LTE. SMS will work over Wi-Fi but MMS will not. MMS requires 3/4G Data.

    I have a Samsung Galaxy S3 model i535 with Verizon logo. I can use it on H2O wireless (a subsidiary of AT&T) and get talk text and data with no problems.
    I changed to tmobile but can only get the talk and text to work...... no data. I have changed/added the tmobile APN without success.

    Can anyone help?

    Have you switched the network mode? And what tmobile apn are you using? They have several, if you are changing the son it's best to try them all and make sure it I s the right one for your device. Like for tmobiOK e a few of them I can remember off the top if my head are named " T-MOBILE--- another one is T-MOBILE US LTE
    , Also under the roaming option have it checked to connect to data services when roaming. make surebyou go to mobile operators after you save the new apn you are using and usually you can just select auto & it will pi CVS k up the network whose sim is in.

    T-Mobile has a entire LTE named apn of course some devices can run in it no problem at all. You would be surprised to OK learn just how many sprint and Verizon phones can work on gsm networks without even missing a beat as long as they are setup right up right. Just goigke how many if them take sins and are capable of running on either and vice verse. Its only a radio bands frequency, it's not that hard to change AM TO FM right? A little bit if a bigger challenge than that on phones, but I am glad for that if phones and computers, and fancy networks didn't malfunction or everybody knew how to do everything with, well I wouldn't have a job

    Ohh and one more thing, if need be root your phone and install the advanced signal status app, it takes you to the see same place as a at&t and tmibile dialer code where you can modify your connection values, but only tinker in there if you know what you are doing obviously.
