MTN Sms's Not coming Through After Port

<p>Good Day</p> <p>I have ported from Cell C to vodacom Last week. Ever since i ported my FNB banking sms's and OTP sms's are not coming through. i Have been in contact with FNB who swear everthing is correct on there side. I have researched the issue online and believe this has occured in the past with a few users due to routing table issues. Please can you assist in this regard to verify and correct the routing with the IT department. As i can see it i am not receiving any MTN SMS's as i have tried from various networks and only the MTN sms's are not coming through. As my new Network provider please assist me in rectfying the issue.</p> <p>Thank You</p>
