I have tested them using uFone only currently (will update others soon)
Note: I have a uth package activated on my ufone and daily sms bundle package activated
Charges per sms for international messages are: 2.99 rs
These are confirmed international sms charges from Pakistan to USA and for Pakistan to Iraq
Please note, if you’ve tried to test it and found the charges to be 3.11, it’s because ufone charges 0.12 rs per balance inquiry.
