I'm staying in the Philippines for three weeks from Australia and have found that in most of the places I've been in Manila so far, 3G data is non-existant with Smart Buddy! I'm paying P300 a week for next to nothing!
I'm sitting at my sister-in-law's place in Paranaque City and in 3G mode, there's no data at all, although I can see the tower from my window, maybe 100m away. GSM data works fine. NAIA is the same, however I did have 3G data at SM City Sucat earlier today.
I was in Bohol for a few days and I always had 3G data working.
It's definitely not the SIM or phone as I have three phones and two SIMs, all with the same problems.
Has anyone else experienced this and (how) have you resolved it?
