Frequently Asked Questions
Do I need to unlock my phone to use an eSIM?
Usually yes. Your phone needs to be carrier-unlocked before it can use a third-party eSIM. Check before you buy.
When should I activate my eSIM?
Most people install the eSIM before the trip and turn on data only after arriving. That is usually the safest setup.
Can I use my regular number while using a travel eSIM?
Usually yes. Many phones support dual SIM, so your main number can still handle calls and texts while the eSIM is used for data.
What happens if I run out of data?
Most providers let you top up in their app. You can also buy another eSIM plan if you need more data.
