Hi Im from the Philippines! Anyone knows how to improve the netwrk signal of SL? i've been using SL for a month already, during this long weekend i went home to Batangas. i noticed i cannot send/received incoming and outgoing sms/calls in my galaxy SL. and it flashes i can only have emergency calls only. im a suncellular user. it doesn't happen to my previous phone (samsung star wifi). i checked the mobile network under settings, i searched for networks, it can only detect Globe. It's also weird because the signal bar on the screen has 2 bars how come i cant use my sun number. i ended up using my old phone (samsung star) during this long weekend so as not to miss important txts and calls. i hope you can help me guys! tnx!
