I got this T999L recently, the phone is apparently unlocked (or so I was told and I don't know what method was used) and able to be used in Mexico with Telcel and Movistar. The phone has baseband UVUBMK4 however no IMEI (if I enter *#06# I get " /02").
Now, when I put a Telcel SIM it works fine right away, calls, msg, 4g data, BUT if I put a Movistar SIM it looks like it reads it as I get the carrier SIM services app and I get full bars, but there's no network, no 4g, no calls (not registered on network) and if I go to the mobile network settings I get "Insert sim card to access network services".
Does this make any sense? is there anything I can do?
I'm sorry if I asked something that was posted before, I really tried hard finding an answer in the forums but couldn't find any.
Thanks in advance
