Pros and cons
Boost Mobile
Pros
- A single prepaid line carries US service and roaming, with coverage across from 90 countries including Japan, Thailand, Turkey, Mexico, the UK and Europe
- Hotspot sharing and 5G are both included, so the same phone can serve a laptop and tablet
- Top-ups are available and the plan is prepaid, so a short trip needs little commitment
Cons
- Roaming data service ends until the next billing period after the included allowance is used, which rules out heavy map and video use abroad
- Unlimited data carries a fair use policy that lowers high speed after a set amount, so the unlimited claim has a ceiling
- Entry price of $10 and price per GB of $10 read high next to the €5 and €1.50 site medians
Saily
Pros
- Covers 200 with regional and global choice for varied itineraries
- Unlimited data is available with features that include unlimited data, 5G and hotspot
- Hotspot sharing is supported alongside top ups for longer stays
Cons
- Starting price listed at €29.66 ranks toward the higher end versus co:sim at $0.79
- Support runs on email, chat and help centre only
- Marketplace setup through marketplace may feel less direct than carrier plans

Questions about each
Boost Mobile
How much does the Boost Mobile roaming add-on cost?+
Global Roaming is a low monthly add-on with a small data allowance and extra data sold per GB. Entry pricing starts at $10 and the price per GB from is $10. A pricier Global Connection bundle adds global talk and text alongside roaming and a separate North America allowance for Canada and Mexico.
How much roaming data is included?+
Global Roaming bundles a gigabyte of data, after which data service ends until the next billing period. That cap suits maps, messaging and quick lookups rather than streaming or long video sessions abroad. Extra data is sold per GB, so heavy use adds cost on top of the plan.
Saily
How much does Saily cost?+
Saily starting price is listed at €29.66. Reference bundles include Japan access priced at €15.99, United States access priced at €20.49, and Europe access priced at €31.99. Travelers can compare these options against trip length and data needs before purchase.
How wide is Saily coverage?+
Saily covers 200 across regional and global plans. That scope suits multi country itineraries where travelers want regional plus global choice without changing provider. Coverage breadth helps when plans span Europe, the United States, Japan, and onward travel.
