Just installed a Huawei B818-263, with an EE Sim, to replace a D-Link DWR-921.
It works well, improving download speeds to 100-200 Mpbs (previously 15-40) with 4G.
But connection of WhatsApp calls between some phones is now impossible. The receiving phone rings but, when answered, no connection can be established. It happens consistently between most pairs of phones but not between some others. It happens with calls via third party routers but my tests were between a variety of different phones (Apple and Android) connected to the same B818 router. I did a factory reset and checked firmware, with no effect.
I reinstalled my D-Link DWR-921 and the problem disappeared. But it came back when I again installed the Huawei B818-263. I have logged this on the Huawei support site.
Has anybody got any ideas because I have run out of them?
I am happy to enter correspondence via this Forum or directly because, not only do I not want to have wasted £200 but the speed of this Huawei device is so impressive. Also, I have a fear that whatever is causing this WhatsApp problem may affect other apps.
So...all help and guidance very gratefully received.
