Yesterday, we had our 2 mobile phone lines of the family transferred from POST to Tango to take advantage of the new infitity offers. However, after activiating our SIM cards we noticed that we have no signal at all in our place. Basically in almost all areas of the village we leave (Eisenborn) there no good reception. Inside the house the signal is zero and only if I get to the attic I can get 1 or 2 bars. On top of that, Tango network it seems that does not support VoWiFi in our devices (Samsung A70 and Huawei P30 lite). Is there a solution for that or we have to switch back to POST?
