Sweden has various major mobile operators in the country that are known for its services and connectivity. These are Vimla, Hallon, Telenor, Telia, Tele2, and 3 (Tre), among others. Hallon is the best of all.

It offers relatively cheap international calls, which serves as a valuable asset for an expat. You will only have to pay for data as all its contracts include free calls and SMS.
