The O2 SIM must be topped-up/activated every 6 months. Since I may not be back in Germany for a year, I plan to top-up via the internet while in the USA. How much must I add to the account to save the SIM? 15 Euros?
Do I actually have to apply a data plan to the Surfstick or just add money to the SIM's account? If I purchase a phone next year in Germany, can I use the same SIM on the phone, just adding a talk plan to the SIM?
