Common questions
Do I need an unlocked phone for a local SIM or an eSIM?
Yes, both require your phone to be carrier unlocked. Most phones bought outright are already unlocked, but handsets bought on a contract may still be locked to your home network. It is worth checking this before your trip, since unlocking can sometimes take a few days.
Can I still receive calls and texts on my home number with an eSIM?
Yes, this is the main advantage of an eSIM over a physical local SIM. Most phones support having both active at once, so your home SIM stays in for calls and texts while the eSIM handles data. A physical local SIM usually means your home number goes offline until you swap the SIM back.
Is eSIM data coverage as reliable as a local SIM?
In most popular destinations, yes, since eSIM providers typically use the same local networks as physical SIMs. Coverage can be patchier in more remote or rural areas, so it is worth checking reviews for your specific destination before relying on it entirely.
What happens if I go over my data allowance?
Most eSIM and local SIM data bundles simply stop working, or slow down significantly, once you reach the limit rather than charging you extra automatically. Home carrier roaming passes vary more, and some can charge substantial overage fees, so check your provider's policy before you travel.
