Question 1

Should I get a local SIM card or use an eSIM abroad?

Accepted Answer

eSIMs are more convenient since you can activate them before arrival without visiting a store. However, local physical SIM cards are often cheaper for long-term stays and may offer better data plans. If your phone supports eSIM, consider using one for immediate connectivity and switching to a local SIM for longer stays.

Question 2

How much does mobile data cost abroad?

Accepted Answer

Prepaid mobile data costs vary dramatically by country. In many Southeast Asian and Latin American countries, you can get 10-30GB for $5-$15/month. European countries typically cost $10-$30/month for similar amounts. Middle Eastern and island nations tend to be the most expensive at $30-$60/month.

Question 3

Do I need to unlock my phone to use a foreign SIM?

Accepted Answer

Yes, your phone must be unlocked to use a foreign SIM card or eSIM from another carrier. Most carriers will unlock your phone for free after your contract ends. You can check if your phone is unlocked by inserting a SIM from a different carrier. eSIM-compatible phones also need to be carrier-unlocked.
