Things has been very frustrating for the past 2 weeks. I got my phone bought unlocked fr dubai and i have been using it here in the philippines since dec 2012. After installing access point and network + my signal has been missing 90% of the time. Cant receive txt and calls , i cant also call and txt. Im not on att and havent upgraded to 1308, ive tried changing sim cards and soft resets multiple times but the signal just keeps on disappearing. Any other international users having the same problem not related to 1308 update ? Any solution youve tried and worked? Pls help me, i need my phone and i love my lumia
