Use tsim’s country specific sim cards, if you are travelling to a single country. These have the highest call rates and local numbers so locals can call you very diffuculte.
My brother using the this sim card, all plans and packs too expensive. And biggested problem is a network problem. Never found full network at anywhere. More than many users not fully happy with this company services. Also company customer services extremely bad guys.
Don’t use this company sim card, already prblems and problems available.
