Mobile Data Not Working.

Mobile Data Not Working.

Hello All,

 

I have an issue. Recently I went on vacation (outside US) and I was using a local sim card there. After I came back to the US and put my AT&T sim card back in, I am facing an issue with my mobile data. Its not working anymore. I am on the $60 plan. I called up 611, and tech support asked me to reset the phone. Sounds a bit extreme, for something like this. Any suggestions on this would be helpful.

Hello muforlife,

Have you ensure that your AP settings are correct, and active?

Re: Mobile Data Not Working.

Which make and model of phone is it??
While you use a local Sim card,do you download / accept any SMS from them ??
In some country, when you use their "Local" Sim card,they will change your setting by doing the above,
and mass up your APN setting.

You just need to switch back your APN in your phone.

Well it turns out the APN settings was incorrect. There are so many different APN's when you google, its hard to know which one is the correct. 

 

Thanks All!
