Best eSIM for a month (2026): 30-day plans from 7 providers compared

For a month abroad, a 30-day plan with a fixed amount of data is almost always cheaper than "unlimited". NomadGB had the cheapest 30-day 10GB plan in 5 of the 7 places we checked (for example $7.49 in Japan and $6.49 in the UK); Nomad was cheaper in Mexico ($15.50) and Ubigi in Europe ($15). If you work from abroad and need lots of data, Maya Mobile's $49.99 for 30 days was the cheapest unlimited month nearly everywhere, with full speed for 5GB a day.

How we compared: we took each provider's 30-day prices from its own website on 13 November 2026 and our own catalog the same week. We looked at 10GB and 20GB plans valid 30 days, the cheapest 30-day "unlimited" plan and its real cap, hotspot rules, and top-ups. We picked seven common long-stay places: Japan, the USA, Europe (regional), Mexico, Thailand, the UK and Colombia. Saily blocks automated price checks and we did not check Yesim, so both are "not checked".

All prices are for plans valid 30 days, data only. Saily and Yesim: not checked. Holafly sells only unlimited plans; its 30-day price was $73.90 in Japan and Thailand, $66.50 in Mexico and $100.50 in Colombia.

What "unlimited for a month" really means

Every 30-day unlimited plan we checked has a cap, and the caps work differently:

• Maya Mobile ($49.99): 5GB a day at full speed, then 3 Mbps. Over 30 days that is a lot of fast data, but a heavy day still slows down.
• Airalo ($49 to $92 depending on country): 3GB or 5GB a day at full speed, then 1 Mbps.
• Ubigi ($44 to $65): 60GB at full speed for the whole month, then 2 Mbps. Good if your use is uneven from day to day.
• Holafly ($66.50 to $100.50): no stated daily cap, but a fair use policy and only 1GB a day of hotspot.
• NomadGB daily plans: we sell daily plans (for example 3GB a day) but at a month's length they cost more than Maya. Our 14-day 3GB-a-day plan in Japan is already $53.99.

Best for each need

NomadGB: cheapest fixed month in most places

Our 30-day plans were the cheapest 10GB option in Japan ($7.49), the USA ($9.49), Thailand ($7.49), the UK ($6.49) and Colombia ($17.99). For 20GB we charge $11.49 in Japan, Thailand and the UK. You can top up the same eSIM if you run out. We lose in Mexico, where Nomad's 10GB ($15.50) and Airalo's ($18.50) are cheaper, and in Europe, where Ubigi's 10GB at $15 beats our $23.49. Our unlimited options are not competitive for a full month. See our global eSIM or pick your country on the home page.

Maya Mobile: cheapest unlimited month

Maya Mobile charges the same $49.99 for 30 days in every country we checked, with 5GB a day at full speed. In Colombia, Mexico, Japan and the USA that is the lowest unlimited price by a wide margin. Hotspot is available depending on the local carrier.

Ubigi: best for a month in Europe

Ubigi has the cheapest 30-day Europe plan at $15 for 10GB, and its UK unlimited month at $44 includes 60GB at full speed. Hotspot is allowed.

Nomad: good in Mexico and the USA

Nomad (nomadesim.com, the getnomad.app company, not our brand NomadGB) was cheapest for 10GB in Mexico at $15.50 and close to us in the USA at $10.40. Its plans are 30 days by default, which suits long stays. It supports hotspot.

Airalo: widest choice

Airalo has 30-day plans almost everywhere and some with calls and texts. For 10GB it is usually above Nomad and us. In Thailand its 30-day unlimited at $49 (5GB a day) ties Ubigi.

Holafly, Saily and Yesim

Holafly is the simplest unlimited option but costs $66.50 to $100.50 for 30 days in the places above. Saily (Nord Security) and Yesim (Swiss, with pay-as-you-go data) are also popular for long trips; we could not compare their prices.

Working from abroad: what to check

• Hotspot: for a laptop, confirm tethering is allowed. Nomad, Ubigi and Maya say yes. Holafly caps sharing at 1GB a day.
• Video calls: a 20GB month covers a few calls a week. Daily calls and screen sharing on mobile data need 50GB or an unlimited plan.
• Phone number: most travel eSIMs are data only. Keep your home SIM on for bank and two-factor codes.
• Top-ups: if you may run out before day 30, pick a plan you can top up instead of buying a new eSIM. Our plans, Airalo and Nomad sell top-ups for many plans.

Which one should you pick?

• A month, normal use (maps, messages, some video): a 10GB or 20GB 30-day NomadGB plan in most places; Nomad in Mexico; Ubigi in Europe.
• A month of remote work: Maya at $49.99, or Ubigi's 60GB month where it costs $44 to $49.
• Laptop tethering every day: Ubigi or Maya; avoid Holafly's 1GB hotspot limit.
• Several countries in the month: a regional plan such as Ubigi Europe or a global plan.
