Telkom Mobile and Samsung S20

[Eltondp]

Hi there,

We have 2 cellphone S8 and S20 on Telkom contract.
Working in Gauteng everything is fine. Driving to remote places can not make any voice calls, "Not registered on the network".
Third phone IPhone on Telkom contract can make calls as normal.
Spoke to Telkom help line three times but they could net sort it out.
Installed a Telkom pre paid SIM in the S20, it was then possible to make calls on that new SIM but 2hr. later it said "Not registered on the network"
