Pros and cons
ByteSIM
Pros
- Plans start at $2.90 and reach from 200 countries.
- Unlimited data, 5G, hotspot sharing and instant activation all appear in unlimited data, 5g and hotspot.
- Reference local plans for the USA, Japan, Thailand, Indonesia, China, South Korea and Australia are sold at the same $2.90.
Cons
- Unlimited plans sit under an international fair use policy, so an operator can cap speed, though any restriction typically clears within a day.
Jetpac
Pros
- Connections come from Vodafone, AT&T and SoftBank, so a handset already on a major carrier usually settles on the local network fast.
- Bought data carries no fair use policy, so the full allowance keeps working at normal speed.
- Top-ups are available, which suits trips that outlast the bought data, and plans suit short trips and longer stays alike.
Cons
- The price per GB of $2 is above the €1.50 median, so heavy data users pay more than the cheaper sellers.
- The cheapest plan, $5, sits above the €2.87 lower end of the market, so a short trip costs more than it needs to.
- Unlimited plans are not uncapped: a fair use policy gives a daily allowance at standard speed, then slower speeds.
Who each suits
ByteSIM
Who it suits
- Travellers on short trips who would rather buy before they fly and switch on abroad.
- People who stream in HD and share a hotspot from the same plan.
- Travellers whose trips mix local, regional and global plans (local, regional and global) and prefer one seller.
Who should look elsewhere
- Travellers who need a top-up mid-trip, since top-ups are not offered.
- Shoppers chasing the lowest entry price, because eSIMGo.is starts lower at $0.99.
- Travellers who want unlimited data with no fair use policy at all.
Jetpac
Who it suits
- Travellers crossing several borders who want one global plan rather than a separate eSIM per country.
- People who need hotspot sharing and 5G on the same plan, or who would rather not meter their data at all.
- Budgets that plan around a set data allowance, with top-ups available for whatever the trip uses after that.
Who should look elsewhere
- Not for the smallest budgets: eSIMGo.is starts at $0.99.
- Not for travellers who prefer a carrier's own pass priced in local currency, such as MTN at NGN 5,000.
- Not for anyone who needs unlimited data with no fair use limit, because a fair use policy slows speeds after a daily allowance.

Questions about each
ByteSIM
What do ByteSIM plans cost?+
Reference plans for the USA, Japan, Thailand, Indonesia, China, South Korea and Australia are all sold at the same entry price of $2.90, and Hong Kong is priced below that. Compared with the site median of €5 for eSIM sellers, that starting figure sits at the lower end.
How many countries do ByteSIM eSIMs cover?+
Coverage spans from 200 countries across local, regional and global plans, so a single trip and a multi-country itinerary can both use the same seller. The catalogue sits well above the site median of 74 countries, though the widest eSIM sellers here reach 259.
Jetpac
How much does a Jetpac eSIM cost?+
Plans start at $5 and the price per GB begins at $2. Europe's larger data tier is $22, the US tier is $19 and Japan is $16. Unlimited plans sit above those prices but spare you from topping up mid-trip.
Is Jetpac's unlimited data really unlimited?+
Unlimited data is offered, but a fair use policy applies. Bought data has no fair use limit at all, while unlimited plans give a set daily allowance at standard speed and then drop to a much lower speed. Heavy streaming after that allowance is spent is where the difference shows.
