I bought a Lycamobile sim-card here in Antwerp and we are leaving tomorrow to go to Germany, Can I still use the sim-card there? And if so, how to reactivate it? What to change in settings?
- Yes, it's possible to continue using the same sim-card
- There's no need to "reactivate" or change anything in the settings, it's all automatic
- Note that you won't be able to use the same plan in Germany, however the charges would be capped by EU legislation at a reasonable level. Again, no need to change or do anything, it's all automatic.
However the best solution is to simply buy a local card in Germany. This may change in 2017 when all roaming fees are banned within the EU, but for now it's still better to shop around.
