A week in London may call for a UK plan with calls and texts. A rail-heavy Japan trip may call for a local-network option with enough daily high-speed data. A five-country Europe trip needs a regional plan whose coverage list actually contains all five countries.

Best Sim Local plan for the UK
The UK is where Sim Local's local-network angle is especially interesting. Current official pages show plans connected with EE, Three and Lyca options, and some explicitly include calls, texts and a UK number. That matters if you are moving to the UK, visiting family, attending an event or simply do not want to explain to every hotel that you only have WhatsApp.
Choose a UK plan with calls and texts if you need:
- ordinary calls to UK numbers;
- SMS for bookings or services;
- a local number;
- a month or more of UK use.
Choose data-only if your calls are all through WhatsApp, FaceTime, Telegram or similar and you only need internet. The cheaper-looking plan is not always the better plan; having a local number can be worth more than a few extra gigabytes for some travellers.

Best Sim Local plan for the USA
For the USA, start with your route. New York, Las Vegas, Miami and Los Angeles are easy data cities. A driving holiday through national parks, small towns or wide rural stretches needs more realistic expectations. Carrier names and coverage are plan-level details, so do not assume every US option uses the same network.
Sim Local's own USA material has shown a mix of Lycamobile, Three and Smartroam-style options, including examples using major US networks. It has also listed plans with calls and texts alongside data-only choices. The correct question is not "does Sim Local cover the USA?" It is "what does this exact US plan include, and where do I need it?"
For a normal holiday, 5–10 GB can cover maps, messages, ride apps and moderate social use. Choose more if you will stream, upload video, use a laptop hotspot or have no hotel Wi-Fi. If you pick an unlimited plan, read the wording around daily high-speed data and tethering.
Our USA Sim Local coupon guide goes deeper on trip length, data needs and US plan checks.
Best Sim Local plan for Europe
Europe is the destination where a vague plan choice causes the most pain. "Europe" may mean 36, 44 or 45 countries on different current plan cards, and the included countries can vary. A plan that covers France, Spain and Italy may not cover a side trip to Switzerland, Turkey, Albania or the UK in the way you expect.
The plan page currently presents a range of data-only and data/calls/SMS choices. That is great for flexibility. It also means you should make a written list of every arrival airport and border crossing, then check it against the exact coverage list before purchasing.
For most interrail-style trips:
- 5–10 GB is reasonable if you rely on hotel Wi-Fi and mainly use maps and messages.
- 20 GB is more comfortable if you upload stories, use translation apps all day and work occasionally.
- An unlimited option may suit a heavy user, but only after checking the daily high-speed amount and whether tethering is permitted.
Use the Sim Local Europe eSIM guide for the country-first checklist.
Best Sim Local plan for Japan
Japan is data-hungry in a quiet way. You will use maps around stations, translate menus, check platform changes, book tickets and navigate city blocks. Offline maps help, but a solid connection removes a lot of friction.
Current Sim Local Japan pages show AU by KDDI and Smartroam options. That creates a useful choice, but do not call every Japan plan identical. One plan may be labelled unlimited for a short period; another may have a fixed data bucket over 30 days. Check the duration and daily high-speed terms rather than making the decision from the word "unlimited".
For a 7–15 day Japan trip, pick the option that clearly matches your arrival and departure dates. If you use video, laptop hotspot or cloud backups, lean toward a larger allowance or a plan with a high daily high-speed threshold. Our Sim Local Japan eSIM guide explains the difference in plain language.
Best Sim Local plan for Thailand
Thailand is a classic eSIM destination because maps, Grab, booking apps and local recommendations are far easier with data. Current Sim Local Thailand pages show options tied to DTAC as well as other product types. Bangkok and Chiang Mai are simple use cases; islands and more remote areas deserve a slightly more cautious expectation.
Choose a short fixed-data plan for a light holiday. Choose more data or an unlimited-style option if you will create content, tether a laptop or spend long transit days streaming. Again, "unlimited" must be read with its daily high-speed rule.
See our Thailand guide for a destination-specific plan chooser.
How much data is enough?
- 1–3 GB: maps, messages, transport, light browsing.
- 5–10 GB: a normal week with social media, travel admin and some calls.
- 15–20 GB: frequent uploads, work, hotspots and video calls.
- Unlimited-style plans: for heavy use only after checking the speed policy and tethering terms.
You can reduce your use without making the trip less fun. Download maps and playlists. Put photo backup on Wi-Fi. Avoid TikTok/Reels autoplay on mobile data. Keep your home line from switching data automatically.

Final pick
The best Sim Local eSIM plans are not one fixed list. They are a smart shortlisting process: local UK plan if you need a number, plan-specific US option for your route, coverage-checked regional plan for Europe, and a clearly explained Japan or Thailand plan for a focused trip.
Apply ESIMADVICE once you have chosen the plan. The discount is useful; choosing the right eSIM is what saves the trip.
