Pls can any member please give me info on how to resolve internet sharing issue on my lumia 900 at%t unlocked nokia phone. I bought this phone from georgia and eversince i started using it in Nigeria, the wifi hotspot has alws been popping up with a message "Contact at%t by visiting www.att.com or call 611 to activate". I read some articles which said that it cant be resolved by entirely flashing the phone firmware to look like a phone produced for Nigeria. That is removing the entire at%t firmware. Can anyone pls give me info cos i really need this internet sharing option activated on my device.
