@MTNza @rainSouthAfrica My number has been stuck in a split-port dead-lock for OVER A MONTH. I can make calls but CANNOT receive calls/SMS (Call Failed). Regular support can't fix this core network routing issue. I have officially lodged a complaint with ICASA. Fix my routing

[ming yang @mingyang970773]

@MTNza Thank you for the apology, ~NPS. But as you can see, this inter-operator routing loop has been broken for almost 2 month, and my financial security is heavily compromised due to missing banking OTPs. CRDB broadcast, Incoming gateway blocking. Before the end of the day today.

@MTNza My issue still hasn't been solved

[ming yang @mingyang970773]

@rainSouthAfrica I'm sorry, I misunderstood My phone is always online

[ming yang @mingyang970773]

@rainSouthAfrica Sorry I just saw the message Already turned off

[ming yang @mingyang970773]

@rainSouthAfrica your technical team cannot ignore this interconnect mail. Please get your Core Network Engineers to check the incoming interconnection mail from MTN immediately, clear the residual routing from Rain's switch, and release my profile NOW!

[ming yang @mingyang970773]

@rainSouthAfrica This officially isolates the issue to Rain's network infrastructure. MTN has provisioned the number, but your HLR/HSS/VoLTE database is still holding stale routing pointers, causing other networks to return 'Number not provisioned

[ming yang @mingyang970773]

@rainSouthAfrica CRITICAL UPDATE: MTN Core Network Has Confirmed Routing Fix. Action Required by Rain https://t.co/q2e5OH3yYC Executive Support has just officially confirmed: "Routing is correctly updated on our side. We have sent a follow-up email to RAIN and are waiting for their feedback.

[ming yang @mingyang970773]

@MTNza Since Rain Support is now actively investigating on their end as well, please immediately notify your Core Network Engineering Team of this ICASA case number. They must manually re-provision my MSISDN and sync the routing tables with Rain today to avoid further regulatory

[ming yang @mingyang970773]

@MTNza Please be informed that ICASA has officially accepted and registered my complaint under Case Reference: CRM:0319590 regarding this one-month-long split-port routing failure.

[ming yang @mingyang970773]

@MTNza Hi MTN Support, reference to my open ticket RITM5021788

[ming yang @mingyang970773]

@rainSouthAfrica Please have your Core Network Engineering Team check your HLR/HSS/VoLTE database to ensure that this number has been 100% deactivated, cleared, and released from Rain's routing network. Any residual routing pointers on Rain's side must be deleted. Thank you.

[ming yang @mingyang970773]

@rainSouthAfrica This is a textbook split-port / inter-operator routing deadlock. MTN's core network team is currently investigating under ticket RITM5021788, and ICASA has been notified.

[ming yang @mingyang970773]

@rainSouthAfrica I ported this number to MTN on 16 September 2026. Outgoing calls work on MTN, but all incoming calls show 'Call Failed' and SMS/OTPs are completely blocked.

[ming yang @mingyang970773]

@rainSouthAfrica database and ensure that my number has been 100% de-provisioned and cleared from Rain's network? Residual routing entries on Rain's side are likely causing this inter-operator deadlock. MTN's active ticket is RITM5021788. Thank you.
