Cheapest eSIM 2026: best under-$10 picks per region

Under $10 still buys a usable eSIM in 2026 — but only in the right markets. Here's the per-region map of where $10 is enough and where it isn't.

Under $5: cheapest possible plans

• Vietnam / Thailand / Cambodia: 3 GB / 7 days for $3-4 on Viettel or AIS networks.
• Indonesia: 5 GB / 7 days for $4-5 on Telkomsel.
• India: 5 GB / 10 days for $4 on Airtel or Jio.

These work great for week-long city trips. They throttle to 256 kbps after the cap — fine for WhatsApp, painful for Maps.

$5-10 sweet spot

• Turkey: 5 GB / 15 days for $7-9 on Turkcell.
• Mexico: 5 GB / 30 days for $8-10 on Telcel.
• UAE / Egypt: 5 GB / 15 days for $9-10.
• Schengen Europe regional: 3 GB / 7 days for $8 across 30+ countries — perfect for a city break across two countries.

Where $10 isn't enough

These markets price 5 GB above $10 because wholesale rates are higher:

• USA: Even basic 5 GB / 30 days is $12-18. T-Mobile and Verizon wholesale rates haven't dropped.
• Switzerland / Norway / Iceland: Premium Schengen pricing. Plan for $15+.
• Japan: 5 GB plans are $12-15. Worth the extra for the Tokyo-subway 5G.
• Saudi Arabia / Kuwait: $14+ thanks to limited wholesale competition.

The "$5 for 1 GB" rule

A quick mental shortcut: in 2026, the wholesale floor for travel data is roughly $1-2 per GB per week in Asia/Africa/Eastern Europe, $2-3 in Western Europe, $4-5 in North America and pockets of the Middle East. If a 5 GB plan costs $5, it's a good deal. If it costs $20+, the country has either expensive carriers or low competition.

Quick verdict

For a city weekend abroad on a budget, $5-10 buys a perfectly usable 3-5 GB plan in most of Asia, the Middle East and Eastern Europe. Browse MobileXY's per-country plans and filter by short durations — you'll find sub-$5 starter packs in 80% of destinations.
