[SOLVED] Wifi routeur and SMS issue

[Infilz]

Hello,
I just bought a tenda AC11 routeur, and when my Iphone is connected to the wifi from the routeur, all my text messages end "not delivered".
it only happens when i'm connected to the tenda routeur. works fine on others wifi.

Is there any paramter i can change to be able to send SMS while connected to the tenda AC11 wifi ?

Thanks for your help

You're saying if you send an SMS message to Mobile A while connected to the tenda you get Not Delivered, but if you send an SMS to that same Mobile A on another wifi network it delivers?

Are the Not Delivered messages to both iPhone and Android devices? Or only Android?

SMS doesn't work over wifi, iMessage does.

- Yes

- Haven't tried on android device, i'll try tonight.

- I know SMS doesn't work with internet, except if you activate wifi call on Iphone.
But obviously, there is some setting that blocks SMS from going through Wifi.

A number of people have reported iMessage failing when Wifi Calling is enabled. Try disabling it, just as a test.

Check that the router isn't blocking VPN traffic, and then that the below ports are open (for wifi calling):

500 UDP
4500 UDP
143 TCP

Possibly 443 and 5223, also used by iMessage

Seems to work, but have to make more tests.
Coming later to give feedback

PS : not totally sure it works....
