Same here, tried to SMS a friend with a VC phone but failed. CellC to VC.
I need some help here, please anyone.
Problem still the same, and i did a test to MTN as well as to my CellC sim on my phone.
Sent sms to VC sim = fail
Sent sms to MTN sim = fail
Sent sms to CellC sim on my phone = fail
Changed modem sim 074xxxxx from my K3520 modem to the E367 modem = fail
Upgraded Mobile Partner = failed to send sms.
The only thing which i cannot test is the cellc sim & support said it's OK. I don't know what to do anymore.
I'm using MPartner for many years now, never had this kind of problem.
Thx.
Just saw USSD also fails.
