Compare by total trip cost
Prices below come from the current Averoam catalogue in USD, before promo codes. Each shortlist includes fixed-data plans covering at least the stated days and data. Longer-validity plans remain eligible. This is a comparison within Averoam, not a market-wide cheapest-price claim.

The lowest total price and lowest price per GB answer different questions. Buy more data when you expect to use it. Unlimited plans are excluded from these fixed-data comparisons because their high-speed allowances and throttling rules can differ.
Check the package before buying
The same destination can have packages from different providers. Read the selected package’s activation deadline, speed restrictions and hotspot policy. A provider name is not necessarily the local mobile network. Where the network is not stated, ask support before relying on specific coverage.

Before you travel
- Check your exact phone model and that it is carrier-unlocked using our compatibility guide.
- Read when validity starts before installing. Some packages start at purchase or installation, others on network connection or data use.
- Keep your home SIM’s data roaming off. Calls and texts on your home line can still incur your carrier’s charges.
- Check hotspot and fair-use terms if you will tether a laptop or stream video.
When another option may fit better
If you need a local phone number, verify that it is included; a data-only eSIM cannot replace that service. If your phone is incompatible or locked, resolve that first. For heavy tethering or a long stay, compare a local carrier’s offer and the exact coverage you need before buying.
eSIMs are non-refundable once issued. See the terms and setup and support FAQ.
