Unable to text friend after he ported his number

[Darola]

My friend used to be on ID Mobile, and has just moved, and ported his number, to Lebara. He can text me, and we can call each other. But I can no longer text him, I just get an error "Not Delivered". I also have a phone on Talkmobile, and another friend is on ID Mobile - both of these devices are able to send and receive texts with my friend on Lebara, its just my EE phone that can not send him texts. 

I read something that EE needs to update its routing tables, so it is pointing text messages to Lebara for his ported number, instead of ID. But I don't know who to contact or how to raise this as an issue.

Any ideas how I can get my EE mobile to send texts to my friend without an error?

Routing tables direct calls with particular prefixes, to the native MNO - who then have porting data for numbers that are ported-out. If calls are working, then that data is in-place.

How long since you haven't been able to text your friend?

[Darola]

About 36 hours now.

Hi @Darola 

Do you have RCS / Chat messaging switched on in your EE phone? 

If so, have you tried sending a message while the setting is switched off?

Yes. I switched it off but still get the same “Not Delivered” message. My friends phone is getting messaged from all other networks now, just not from EE.

@Darola 

Is that the same if you both reply to an incoming message and a freshly created message? 

Have you been able to test this with your EE SIM card in a different phone?
