ByteSIM eSIM review
The short answer. ByteSIM sells prepaid travel eSIM plans in 185 countries, and its cheapest rate today is $0.58 per GB. Its median rate of $2.00 per GB is about 27% below the $2.75 median across every plan we track. On price it is a reasonable default, and the country page for your destination will still show you whether someone there beats it. It also sells plans marketed as unlimited, the most generous of them allowing 10 GB a day at full speed.

Have we checked these prices?
93% of ByteSIM's plans on this site were checked against ByteSIM's own shop on 19 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.
- Confirmed on sale at our price8,558 plans
- Price corrected to theirs2,599 plans were listed here at a price that had moved
- Removed from the site123 plans we could not find on sale
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 ByteSIM?
ByteSIM sells travel data in more than 180 countries and runs one of the largest catalogues we track, over twelve thousand plans once you count every size and duration combination. The shop is built on Shopline, payment is by card, and there is a mobile app for managing plans and checking usage.
What makes them worth reading carefully is the shape of their range rather than the size of it. Most sellers offer you a pool of data. ByteSIM offers three different things and names them in a way that is easy to misread: a fixed pool written as "Total 10GB", a daily allowance written as "1GB/Day", and genuinely uncapped plans written as "Unlimited Data". A ten day plan at 1 GB per day is ten gigabytes of full speed data, not one, and a fixed 10 GB plan over ten days is a different product at a different price. We store all three separately so the tables compare like with like, and where a description was ambiguous we left the plan out rather than guess at it.
They also sell a number of country plans that include local calls and SMS, and a handful of carrier specific premium plans such as Japan on KDDI and South Korea on LG U+. Those are real distinct products rather than marketing labels, and they are priced accordingly.
How ByteSIM works, in detail
Is there a ByteSIM discount code?
Not one we can vouch for right now. We only publish a ByteSIM promo code after testing it at ByteSIM'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 ByteSIM ranks in our tables.
Why ByteSIM scores 4.7 out of 5
No editor chose this number. It is computed from three measurable things, weighted 45% value, 35% coverage, 20% features:
Value compares ByteSIM's median price per GB ($2.00) with the market median across every plan we track ($2.75). Coverage counts the 185 countries in its catalogue. The score updates automatically whenever prices change.
PROS
- One of the widest catalogues we track, over 12,000 plans across more than 180 countries
- Three genuinely different plan shapes, so a long trip can use a daily allowance rather than an oversized pool
- Durations are unusually granular, often every few days rather than only 7, 15 and 30
- Named network partners on premium plans, including KDDI in Japan and LG U plus in South Korea
- A real app for installation and usage, and no identity checks
CONS
- Plan naming invites mistakes: Total 10GB and 10GB/Day sit next to each other and mean very different things
- Their regional bundles name a country count rather than the countries, so we do not publish them
- A small number of plan descriptions were too ambiguous to classify and were left out rather than guessed at
- Their own shop sits behind bot protection, so our daily price check reads the feed they publish rather than the storefront itself
Too early for a verdict on ByteSIM
We found no verified customer reviews on Trustpilot yet, so reputation cannot influence this rating. Until a track record builds, here is what to check yourself:
Most praised
- Very large catalogue with unusually fine grained duration choices
- Daily allowance plans suit long trips better than a fixed pool
- Named carrier partners on premium plans
Most complained about
- The naming of fixed, daily and unlimited plans is easy to confuse at a glance
- Regional bundles do not list which countries they cover
- Prices vary widely between plan shapes for the same destination
Check before you buy
- Read the plan shape before the price. Total 10GB is a pool for the whole trip; 1GB/Day is a fresh allowance every day and usually the better deal on a long stay
- Unlimited on some plans means unlimited, and on others means full speed up to a daily amount and slower after. Both appear in their range
- Their regional packs, Europe, Asia, Global and the rest, are not listed here because the feed never says which countries they include
- Premium carrier plans such as Japan on KDDI cost more than the standard Japan plan and are a different product, not a different label

Does ByteSIM sell unlimited data plans?

How do I install a ByteSIM eSIM?
QR code after purchase with automatic activation on arrival. Their product pages state the network partner per destination. 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 ByteSIM 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.
