Galaxy SIII - Poor 4G connection and poor calling signal

Just renewed my contract...was not so exited to do so.  Anyways I decided to renew and got the Galaxy SIII.  Nice phone, but bad connection.  4G keeps gping into Edge and phone signal is poor.  Have to move around the house to get the service.  Hope this issue gets solved soon.  Really would like to stay with T-Mobile.  Have one more week to go and see what happens.

    I would normally ask whether you are using the latest SIM card, but you have no choice with this device as it uses the micro SIM.

     

    • What's your signal like outdoors?
    • How does the signal performance compare with your previous device in your home?
    • Are there any other TM devices you can use to test whether it's a general problem with the tower rather than a specific problem with your device?
    • Have you done a factory reset?

     

    Since you have renewed your contract to get this device, you are tied in for another 24 months (or pay a $200 ETF), even if you return this device within the stipulated period. Let's hope you can get this working to your satisfaction.

     

    I don't think it's a general problem with the design. I used to have constant problems with my previous device flip-flopping between EDGE, 3G and 4G at my home, but the S3 has been pretty consistent in maintaining a 4G signal. That's not to say that there isn't an issue with your device...

    Thank you for your advice.

     

    Okay… went into my account on my phone and then into Device Support.  Followed all the steps in Connectivity Issues and it still has poor signal.  Planning on calling the company during the day.

     

    I rather pay the $200 than being tied to a contract with an expensive phone that doesn’t work.  It’s ridiculous.

    I've got the same issue....my SG3 keeps going from 4g to edge, this goes on constantly throughout the day. It's even more annoying because it actually stays on edge longer than 4g.

    press *#*#4636#*#* at the dial pad then select device informationthe scroll down and at the menu that says "Set preferred network type:" select wcdma only and you will always have 4g but remember this if you are on a area that 4g is no available you will have 0 signal you will have to make this process again to have signal and select GSM auto i hope this helps you
