Free eSIM and Our $5 Credit
Honest take: what's actually free, what isn't, and exactly how our $5 welcome credit works.
Last updated: 2026-05-19
“Free eSIM” is one of the most searched travel terms — and one of the most misleading. Most plans marketed as free either cap you at 100 MB, throttle you to dial-up speeds, or ask for card details upfront with auto-renewal. Below is what’s actually free in the eSIM space, exactly how our $5 welcome credit works (with its rules), and what to avoid.
Is there really a free eSIM?
Sort of. Three things get marketed as “free eSIM,” and only one is genuinely free:
1. Free trial packets (usually 100–500 MB). A handful of providers hand out a starter packet — typically 100 MB to 500 MB valid for 7–30 days. The data is real, but the cap is tight. 500 MB lasts about an hour of YouTube on low quality, or one day of light maps + messaging. After that you pay normal rates.
2. “Free” plans that require a card on file. These ask for your payment details before issuing the eSIM. The plan itself might be free, but auto-renewal kicks in after 24–48 hours. People forget, get charged $15–$30, and learn the hard way.
3. Throttled “lifetime free” eSIMs. A few providers offer unlimited free data at 128 kbps or slower. Slower than 3G from 2008. WhatsApp text works. Maps barely load. Anything image-heavy is unusable.
Honest answer: there’s no truly free eSIM that gives you usable data without strings. The closest thing is a real discount on a paid plan — which is what our $5 welcome credit is.
Simsimsim’s $5 welcome credit — exactly how it works
We don’t give out free money. The $5 welcome credit is a discount on your first purchase, with one important rule:
The $5 credit applies only to plans of $5 or more.
That’s an anti-abuse threshold — without it, anyone could create dozens of accounts to grab the cheapest $2.90 plans for free. The rule keeps the offer real for travelers actually buying meaningful plans, and keeps it sustainable for us.
What this means in practice
| Plan you buy | Plan price | Credit applied | You pay |
|---|---|---|---|
| Japan 5 GB / 30 days | $15.90 | –$5.00 | $10.90 |
| Spain 5 GB / 30 days | $9.90 | –$5.00 | $4.90 |
| USA 10 GB / 30 days | $19.90 | –$5.00 | $14.90 |
| Europe 5 GB / 30 days | $11.90 | –$5.00 | $6.90 |
| Turkey 1 GB / 7 days | $2.90 | does not apply | $2.90 |
If your trip needs a small plan (under $5), the credit doesn’t help on that specific purchase — but it’s still there waiting for a larger plan if you buy a top-up or another country later.
What the credit is not
- Not cash. You can’t withdraw it.
- Not a free plan. Even with the credit, every order over the threshold still has a balance you pay by card, Apple Pay, Google Pay, or crypto.
- Not stackable. One credit per new account. Sign up once, use once.
- Not transferable. Tied to the email you signed up with.

These are below the $5 threshold, so they’re full price — listed here so you know exactly what you’d pay:
| Destination | Smallest plan | Price |
|---|---|---|
| Turkey | 1 GB / 7 days | $2.90 |
| Thailand | 1 GB / 7 days | $2.90 |
| Indonesia | 1 GB / 7 days | $2.90 |
| Mexico | 1 GB / 7 days | $2.90 |
| Egypt | 1 GB / 7 days | $2.90 |
| Vietnam | 1 GB / 7 days | $2.90 |
| Georgia | 1 GB / 7 days | $2.90 |
| Brazil | 1 GB / 7 days | $2.90 |
| India | 1 GB / 7 days | $2.90 |
| Philippines | 1 GB / 7 days | $2.90 |
If you want to use the welcome credit, pick a larger bucket (3 GB / 5 GB / 10 GB) — the price crosses the $5 threshold and the credit kicks in. Often the per-GB cost on bigger plans is lower anyway.
Want unlimited-style data? Daily plans now live
If you came looking for “unlimited eSIM,” here’s the honest version: nobody actually sells truly unlimited mobile data. Every “unlimited” plan on the market — Holafly, Saily, Airalo — has a fair-usage cap. After you hit the daily allowance, your speed drops to a throttle (usually 384 Kbps to 1 Mbps).
We now offer the same model under a more honest name: Daily Unlimited. You pick a daily allowance (1 GB, 2 GB, 3 GB, 5 GB, or 10 GB per day at full LTE/5G), and after that quota you slow to FUP speed until the next day’s reset. Available in 175 countries.
Sample 30-day Daily Unlimited prices:
| Destination | 1 GB/day | 3 GB/day | 10 GB/day |
|---|---|---|---|
| United States | $61.90 | $178.90 | $231.90 |
| United Kingdom | $27.90 | $186.90 | $99.90 |
| Japan | from ~$45 | varies | varies |
| Spain | from ~$28 | varies | varies |
The FUP throttle speed is shown upfront on every country page — we don’t bury it in the footer. Browse 186 destinations to see Daily plans for your trip.
Beware of “free eSIM” scams
Three red flags to walk away from:
1. Asking for full card details before issuing a “free” eSIM. Legitimate trials don’t need your card. If they do, assume you’ll be auto-billed.
2. Demanding personal data (passport, ID, address) for a free trial. Genuine providers need an email at most. Anyone asking for ID upfront is harvesting data — possibly to resell.
3. Sketchy domains and lookalike sites. Watch for domains that mimic big brands with extra hyphens, suspicious TLDs, or no HTTPS. If the site has no terms of service or no contact info, close the tab.
A real provider tells you exactly what you get, what it costs, and how to cancel. Anything murkier than that isn’t worth saving $3.

FAQ
Is the $5 credit a one-time thing? Yes — one per new account, one use. It’s a welcome offer, not a recurring discount.
Can I split the $5 across two plans? No. The credit applies once, in full, to a single qualifying purchase ($5+).
Can I use it on a $2.90 plan? No. The plan must be $5 or more for the credit to apply. This is the anti-abuse rule.
Can I withdraw the $5 as cash? No. It’s a discount on your first eligible purchase, not a cash balance.
What if I buy a $5.90 plan — do I get $4.90 of credit back? No, the credit doesn’t roll over. It’s a flat $5 off a single eligible plan, used once.
Can I get a refund if I don’t use the eSIM? Yes, within 180 days as long as the eSIM hasn’t been activated. We refund what you actually paid (the post-credit amount) to your original payment method. See our refund policy.
Do you have a totally free trial like other providers? No, and we’d rather be honest than dress up a 100 MB throttled packet as “free unlimited.” The $5 credit is real money off a real plan — not a fake-free trap.
Do you offer unlimited data plans? We offer Daily Unlimited — pick 1 GB / 2 GB / 3 GB / 5 GB / 10 GB per day at full speed, then a throttle (usually 384 Kbps) for the rest of that day. Same model as Holafly’s “unlimited,” just with the FUP shown openly on the product page. See any country page — the Daily Unlimited section appears for 175 destinations.
