I am a South African and have been living in the UK for the last 6 years. I’ve been here in the UK with Orange as service provider, using the same mobile number from 2004, with no issues until my frustrations started 2 weeks ago.
All of a sudden I do not receive SMS messages from MTN numbers in South Africa but the same MTN users can receive my Orange SMS messages. I can send SMS's and also receives SMS's locally from the UK and internationally from Europe, New Zealand, Australia etc.
At first I thought the problem must be with Orange but now I have my doubts as my Orange number in the UK can receive SMS's from Vodacom in SA, but not from any MTN number (including my bank (ABSA) who use MTN for sending me SMS notifications for online banking). Other Orange numbers in the UK can receive my MTN-originated SMS's. I have determined that it is definitely not my phone or SIM card.
To make the problem even more complicated – I was on a Orange pre-paid contract for 5 years and then went on Orange pay-as-you-go for a few months and then 3 weeks ago back to Orange pre-paid contract. Orange is convinced that the switch-over from pay-as-you-go to pre-paid 3 weeks ago has nothing to do with the current problem and that it is just a coincidence. Orange escalated the issue to the highest support levels in their applications and networks departments and have now told me that it is definitely an issue with the MTN network in South Africa so Orange is going to close the call as they can’t do anything else to resolve the issue.
My brother in South Africa tried to escalate the issue within MTN but it is so difficult to find a MTN support number that works and if you eventually do manage to talk to a customer services person the only help they give is “I can see the SMS messages are in “pending” status on MTN network and nothing else they can do”.
This is very frustrating and I’ve ran out of ideas now on how to do any further fault finding for the issue.
Anybody out there that is experiencing the same issue at the moment or in the past?
Anyone out there who is an MTN-insider who can suggest how I get MTN to check this problem out?
