Does your iMessage work via your cell number. Not via your apple id. ?
Mine will not activate on my cell number. Im 100% sure it is a sms routing problem , as usual , telkom mobile support is useless.

No seems my imessage is not activating either.....

Welcome to the club.
What about normal sms. Does it work after roaming on MTN abd then reverting to 8ta without a reboot ?

Yes that works fine. I manually changed to MTN network. Then I switched the slider back to auto. Waited some time and it switched back to TelkomSA and send a sms to another network and it went through....

imessage is a bust though. Looks like we need to complain on hellopeter. I see a couple of complaints there and here on mybb about this issue... I don't use imessage but if I find a fix will let you know. :)

It could be iPhone problem. There are two separate methods of sending SMS using different technologies. I talk about standard GSM SMS (not iMessage).
1. Using old CS (circuit switched) GSM services.
2. Using PS (packet switched) GSM services.
It is possible that one network is not supporting both. Iphone switches to a different method when roaming and fails to revert to default when going back to home network. In other scenario iPhone switches back to home network for voice (CS service) and still roaming using data (PS service). There are reports in other thread that phone is continuing consuming all network data bundle instead of on-net bundle. It might be related to the same problem. Unfortunately there is no way to test above theory on iPhone, but you can try to disable LTE and see if any difference.

On other handsets you can chose service for sending&receiving SMS: CS, PS or both. Then if somebody with TM SIM want to take experiment, there is how to do it:

Step A: In TM coverage area use manual network selection and chose TM, then:
1. Change SMS settings to CS only and try to send SMS
2. Change SMS settings to PS only and try to send SMS

Step B: Outside TM coverage use manual network selection and chose MTN, then repeat 1&2 a/a.

Post here which method of sending SMS failed.

So much for trying to get imessage fix with facebook support....

"Hi Eugene. We have checked your number and everything is active, please make sure you are in a Telkom Mobile covered area when activating. If you are roaming on MTN it will fail but as soon as it is activated it will allow you to roam on MTN without failing. Please find link to check your telkom covered areas: http://www.telkommobile.co.za/coverage/"

I would suggest you sending them the hellopeter link. Im convinced it is a routing problem
