Using
O2's international coverage check, it gave this info under the network specific information for Panama:
"You can use GPRS data services and media messaging on this network.
O2 customers roaming on this network will not be able to use 3G services."
Nepal and Peru also say you will not be able to use 3G services but with no mention of GPRS at all. These countries may simply not have HSDPA or UMTS, but still have GPRS or EDGE, which is all you need for sending SMS as mentioned in this thread. I would guess that's the case but it would be worth inquiring if you're headed to one of the above mentioned countries - except Myanmar, which only seems to have one network at this point and
no realistic options for phone service as a foreigner.
