Hello,
I am planning a long trip abroad to Zone4 tariff, specifically in Taiwan. And during this time period, I’d still like to receive SMS and calls on my German phone number, especially for receiving app authentication numbers etc.
Do I need to purchase any additional package to have this work?
And if not, do I only need to turn on Roaming on my O2 German SIM card while I am in Taiwan? Do I need to have the roaming on all the time? In order to save money, I am wondering if it’s okay I just turn the roaming on minutes before I know I am about to receive an SMS or a call from Germany?
Thanks a lot in advance for any input and suggestions!
