Here I offer to you weekflats for internet use with German O2 prepaid sim cards. Just topup the sim for the weekflat the same way as a topup of money. The dayflat is always valid from the text-message confirmation until midnight of the 7th dayand contains a full speed access for one gigabite per day, Maximum 5 gigabite per week. After using this gigabite the traffic will be reduced to GPRS.
Please notice: This item does only work in combination with an O2o or an O2go data sim card, not with the actuall tariffs like O2 Loop or O2 LOOP smart.
