I finally upgraded my Lumia 800 to a Lumia 620 on Straight Talk. Everything is working great except Internet Sharing. I keep getting a message "No mobile data connection". I got this phone on Amazon and suspect it was unlocked from an overseas carrier? The carrier info in settings shows 'CV Malaysia'. Anyone got any ideas?
Internet sharing on my att 620 worked for a bit and then stopped. It is an IMEI issue and said that they couldn't get my 620 to work with both visual voicemail and internet sharing at the same time. It had to do with something about if my 920 imei was on profile, my visual voicemail will work, if i used my 620 imei, my vv would not, but my internet sharing would. I have no idea why, but that was the case.
I chose VV since taht was most important to me vs internet sharing.
