Almost all SMS show as "Not Delivered" when connected to Fizz EXT?

When connected to the FIZZ network everything works fine however when connected to FIZZ EXT my iphone says sms messages are not delivered. Apparently the messages are getting through but its hard to trust when my device says they are not sent. Receiving is hit and miss, some get through others do not. Is there a setting i need to check or is this an ongoing bug?

  • I don't suppose your iPhone needs an update? If they're getting through that's good, but it would be better if your phone knew it too. I haven't had any trouble with sending sms on Fixx Ext.
  • Everything is up to date, my os is 12.1.2 and the carrier is Fizz 35.0. So it has to be something else.
