i’m from korea. arrived 29th jan. at frankfrut.

bought sim at o2 shop in airport.

1. 7.5GB data only sim - 50euro
2. 7.5GB data + voice/sms sim - 50+10euro

problem

high-speed data exhausted so quickly. (2.5days, it’s impossible as my usage habit.)

and cannot send sms

so i went to another o2 shop in zeil street.

recharged 5GB data and activated. (30euro)

but it doesn’t work!

what is my problem?

note) instead of your sim, i bought vodafone sim at rewe market(9.99euro). it does it’s work very well while 3 days and still.
