I have a Realme 7 Pro, and I use a Lebara mobile operator that uses Vodafone networks.
Recently, it suddenly stopped accepting and receiving calls. The mobile connection shows some bars, but when I try to call it is not coming through.
Customer support there is almost non existent, but if I play a detective with lots of missing information I suspect it may have stopped due to phasing out of 3G networks. My other service - Boost (Telstra) works just fine on the same phone, and this Lebara service works on other phone (Motorola 30 Pro).
I suspect it is due to the fact that Lebara requires some VoLTE protocol which is not supported by Realme. Although realme states thye support VoLTE by default and it seems to be working with Boost.
Is there any way to make it work without changing mobile phone or mobile operator? Thanks
PS I saw some instructions for OnePlus phones but mine is a different brand.
