Hello
@steveTu,
Thank you for your patience in this matter.
Three UK have now concluded their investigation on the matter.
The updated response we received on their findings were:
"The SMS Delivery service which we offer supports delivery to landlines via our Text-to-Speech platform. The only exception is P2A SMS which terminates on AQL-enabled SMS landline numbers. Message termination (in SMS form) to landlines is not supported for any other destinations."
To summarise, Three UK have confirmed they cannot support the delivery of a text to text on landlines and it is currently being delivered as text-to-speech. This is a limitation with their current systems. We've requested Three UK to test multiple ways to see if they can enable this service in the future, however, as of now, they have advised us they are unable to fix the issue with their current systems.
Now that we have raised the issue to Three UK, we hope that they can fix/enable this in the future, however, as of right now they are unable to offer this service.
We don't have any further information we can provide on this and if you do have any further technical queries, we'd recommend contacting Three UK directly for this as they have confirmed it is from their end and not iD Mobile's fault.
Whilst I can understand that this may not resolve the actual issue you're facing (by enabling the text-text you require), we do feel this does answer the original post you raised.
We are therefore marking this topic as resolved.
