I am an EU citizen visiting a different country now (but still in EU), in the country's capital. For my travels I have bought a data pack from my provider (I don't have/use data otherwise). Now whenever I turn mobile data on, I only get EDGE connection. My provider's helpline assured me that the data pack I bought is supposed to be 4G. It is a major provider in my country and on the helpline they claimed that 4G should be available in the area I am visiting right now. They have advised me to manually select a different local cellular network.

I tried to go to the Settings, Mobile Network and choose the network manually -- I saw that there were several 3G and 4G networks from various local providers around me with a good signal strength. However, whenever I choose a network to connect to, the connection fails (it says Unable to connect under the network name) and I get a system notification from Phone Services (or is it Cellular Services? Sorry, my phone is not in English) which claims: No signal. The chosen network ( (xxxxx)) is not available (where the x's are always a different number, depending on the chosen network).

The only way I can connect to a cellular network is to choose an automatic connection in the Settings but it always connects me to EDGE. I have also verified that my preferred type of cellular network is set to 4G/3G/2G.

My phone: Xiaomi Mi A3, Android 11 (Android One). The SIM supports LTE.

Do you know what could be the problem and how to solve it?

  • You can check again with your mobile operator about FPLMN (forbidden mobile operators). This is something managed by home mobile operator and is located in SIM card. Commented Sep 21, 2021 at 14:16
