My son just moved to Aus and went and setup a new connection Telstra, he can txt everyone here in NZ, but me, (I'm on a 2 Degree work business plan). His partner's new connection (also setup today), can txt me just fine. I've checked his new Aus number didn't get blocked by spam, (it didn't), and as his partners new connection can txt me just fine, I'm pretty sure it's not blocked call related.
When he tries to txt me, his iPhone 16 pro, (with all the latest updates), immediately says call failed, if I txt him, he does get them.
We have tired all the obvious things, (reboots etc) but before I send him back to the Telstra shop, I thought I'd ask if anyone has had a similar issue and managed to solve it.
Thanks
