Sim Local Discount Code ESIMDISCOUNT10: Sizing Your Data Plan First

Pick the allowance before you chase the discount

The ESIMDISCOUNT10 code takes 10% off a Sim Local travel eSIM order at online checkout. That is a useful trim, but it is a percentage of whatever you have already chosen, so the bigger decision is the plan itself. On the US line-up tracked for Sim Local, plans run roughly $4.00 to $67.00, with data allowances from 500 MB up to 30 GB and validity periods starting at one day. Ten per cent of a $4 plan is about $0.40; on a $20 plan it is around $2; on a $67 plan it is about $6.70. Choosing an allowance one tier too large wipes out the saving several times over, while choosing one too small leaves you buying a top-up mid-trip.

Match validity to the trip, not just gigabytes

Sim Local plans are sold by validity period as well as data volume, so a plan has to cover both how long you are away and how heavily you use data. Validity typically starts on first connection abroad, though this varies by carrier, which matters if you install early and travel a few days later. Sim Local promotes full-speed daily allowances rather than throttled "unlimited" data, so the headline figure you pick is the one you should expect to get, and running past it is not the same as slowing down on an unlimited plan.

Single-country or regional

On simlocal.com, the Destinations section and the destination search box let you compare regional plans against separate country plans. For the US the trackers list eight single-country plans and six multi-country plans. If your itinerary crosses borders, one regional plan may be cheaper than two country plans — and since only one code applies per order, a single well-chosen plan often beats stacking several small ones. There is also a homepage recommendation tool that generates personalised plan suggestions if you would rather start from your trip details.

Check the phone before you check the price

No allowance is the right one if the eSIM will not install. Use Sim Local's compatibility checker and confirm the handset is carrier-unlocked. Phones can usually hold around ten eSIM profiles, though some devices cap storage. You keep your existing number and physical SIM alongside the eSIM, and a data-only plan will not give you a local number — some Sim Local plans include calls, texts or a local number, so check that if you need one.

Applying the code once the plan is chosen

Select your country or region and compare regional against single-country plans.
Confirm device compatibility and unlocked status.
Choose the plan by validity period and add it to the cart.
Continue to checkout and expand the discount code field, sometimes hidden behind an "add a discount code" link.
Type ESIMDISCOUNT10 exactly, with no spaces and no lowercase, then press Apply.
Check that a discount line shows and the total has fallen by 10% before paying.
Enter email and payment details, then install via the app or the emailed QR code and instructions.
Set the eSIM as the data line, turn data roaming on for that line, and turn home SIM data roaming off.

Applying the code is easier when signed in than as a guest, and it is an online-checkout mechanism only — it is not for purchases in Sim Local's airport stores, of which there are more than 100. Because eSIMs are digital, there is no shipping cost to offset.

Where under-sizing costs you

Top-ups are available and handled inside the app, but a top-up bought later as a separate transaction may not carry the same discount, and the 10% cannot be added retroactively after payment. Four $25 plans in one basket would make a $100 order and save $10, though whether a single code spreads across multiple plans in one basket is not stated — confirm it on screen. Any per-order minimum is also not stated, so check the plan page and the terms shown next to the discount field.
