I’ve got a ZTE Kis3 which has suited my needs since 2014. However for about a year the cell service seems to cut out a lot more than usual. I’ve tried using Whatsapp for calls but that’s useless as I can’t hear the other person or vice versa. WIth various people I’ve not had one clear call.
I’m based in the UK and have been using Virgin’s Hub3. It had issues which I sort of resolved using a Belkin N wireless router. However the wifi was inconsistant (devices would only sometimes connect) so I switched back to the Hub3. With either of them, calls on Whatsapp were hopeless. I haven’t tried calling using my data plan as I assume it would only be worse than wifi.
The phone is running 4.4.2 and I can’t update any further. I’m wondering if I need a 4G phone. Over wifi I can watch youtube videos and browse and that’s fine. It’s just calls I’m having issues with. Is there anything I can do to improve calls or could this very much be a phone issue?
