Mobal eSIM review
The short answer. Mobal sells prepaid travel eSIM plans for one country, Japan, and its cheapest rate today is $0.54 per GB. Its median rate of $1.16 per GB is about 8% below the $1.26 median across other sellers' Japan plans of 3 GB to 100 GB. Anywhere but Japan it is no use to you, so it is worth a look only if Japan is the whole trip.

Have we checked these prices?
100% of Mobal's plans on this site were checked against Mobal's own shop on 16 October 2026, one country page at a time. We confirm the product is on sale and that the price is the one they charge, and we take their price over ours whenever the two disagree.

A feed is not a shop. Feeds can list products that are not on sale, describe them differently, or carry a stale price, so a price nobody has checked again is only a number we copied.
Who is Mobal?
Mobal is the odd one out in the best possible way. A trading brand of Mobell Communications, a UK company serving international travellers since 1989, it is owned by the Krizevac Project, a registered UK charity, and states that its profits fund school meals for roughly 14,469 children a day in Malawi. In 2025 it won the King's Award for International Trade.
The product focus is Japan, done properly: tourist data eSIMs from 3GB to 100GB, an unlimited 5G eSIM on the KDDI au network priced per day, and something almost no travel eSIM offers, monthly voice plans with a real Japanese 070/080/090 phone number on Docomo, which residents and long stayers genuinely need.
There is no app; everything runs through a web portal, and voice plans legally require ID under Japanese law. Its Trustpilot sits at 3.9 from a modest 946 reviews. Pricing is mid pack in our Japan tables, and what you are buying alongside the data is four decades of Japan specialisation and a supply chain that feeds children.
How Mobal works, in detail
Is there a Mobal discount code?
Not one we can vouch for right now. We only publish a Mobal promo code after testing it at Mobal's own checkout, and most codes on coupon sites are expired or never worked. If a working discount code appears it will be listed here, and it will never change where Mobal ranks in our tables.
Why Mobal scores 2.8 out of 5

Across other sellers' Japan plans of 3 GB to 100 GB the median is $1.26. Coverage counts the 1 country in its catalogue. Service reflects its independently collected Trustpilot score. The score updates automatically whenever prices change.

Can I use a Mobal eSIM as a hotspot?
Tethering on data and voice+data plans. Generous hotspot use on the unlimited 5G eSIM.
Does Mobal sell unlimited data plans?
23 of its 32 plans are sold as unlimited. In practice they are fair use plans: full speed up to a daily allowance, then slower. That is why they carry no price per GB in our tables.
How do I install a Mobal eSIM?
No app. Access code entered on Mobal's web portal, then QR or manual install. Days start at activation, not order date. Buy the plan online, scan the QR code on wifi before you fly, and leave the new line switched off until you land. Then turn on data roaming for the Mobal line and give it a minute to attach to a network. If the code will not install, our guide to eSIM QR code errors covers every message a phone can show.
