How it works
- Pick your destination and plan. A fixed bundle of data, or an allowance every day. Prices are live — what you see is what you pay.
- Install in a minute. We email a QR code and a one-tap install link. Install before you fly, on your normal wi-fi.
- It starts when you land. Your plan begins on first connection abroad, not at purchase. Buy weeks early if you like.
Fixed data or daily data?
Fixed data
One bundle of GB, valid for a set number of days.
- Best when you roughly know how much you use.
- Runs out? Top up any time — even at 0 GB.
- Or turn on auto-renew and stop thinking about it.
Daily + throttle
An allowance every day at full speed; after the daily cap it slows down instead of stopping.
- Best for long trips and heavy days.
- You are never cut off — just slower until the next day.
- Staying longer? Extend the days.
Not sure? Start with fixed — you can always add more.
A note on “unlimited”: most unlimited travel eSIMs are a daily allowance at full speed, then a slower connection for the rest of the day. That is a normal, reasonable design — but it is not unlimited full-speed data. We show you the daily cap and the speed after it, on every plan, so you can judge it yourself.
Why bidaiesim
Every price is fetched the moment you look, and re-checked before you pay.
Where a plan has a daily cap or a fair-use limit, we show it on the plan itself.
No reinstall, no second QR — add data to the eSIM already in your phone.
Off by default. Turn it on and we add data before you run out; cancel any time.
Regional and global plans cover a whole trip on a single install.
Your usual SIM stays active for calls and texts. The eSIM only carries data.
Will it work on my phone?
You need an eSIM-capable, carrier-unlocked phone. That covers every iPhone from the XS (2018), Google Pixel from the 3, and Samsung Galaxy from the S20.
Check in ten seconds: dial <code>*#06#</code>. If you see an EID number, your phone supports eSIM.
Locked to a carrier? Ask them to unlock it — an eSIM cannot get around a carrier lock.

Common questions
Will this work on my phone?
You need an eSIM-capable, carrier-unlocked phone — every iPhone since the XS, Pixel since the 3, Galaxy since the S20. Dial *#06# and look for an EID number: if it is there, your phone supports eSIM.
When does my plan start — when I buy it, or when I arrive?
On first connection abroad, not at purchase. You can buy weeks ahead and install at home on wi-fi; the clock only starts when the eSIM first connects to a network at your destination.
Can I keep my normal phone number?
Yes. Your usual SIM stays active for calls and texts, and the eSIM carries only data. Turn off roaming on your normal line to avoid your home carrier's charges.
What happens when I run out of data?
Nothing breaks. You can top up the same eSIM at any point, including at 0 GB — no reinstall and no new QR code. You can also switch on auto-renew so we add data before you run out.
Can I get a refund?
Yes, in full, any time before you install the eSIM. Once it is installed or activated we cannot take it back, because the plan has been issued. If it is installed but not working, contact us and we will sort it.
Is “unlimited” really unlimited?
Usually not, anywhere. Most unlimited travel eSIMs give a daily allowance at full speed and a slower connection after it. That is a reasonable design — we just show you the cap and the speed after it so you can judge it yourself.
Which networks will I actually be on?
We list the real operators for each plan and country before you buy — not “premium partners”. Which one you attach to depends on coverage where you are standing.
Can I use one eSIM in several countries?
Yes, with a regional or global plan: one install covers the whole trip. A single-country plan only works in that country.
Can I use it as a hotspot?
On most plans, yes, and we do not charge extra for it. Tethering uses data much faster than a phone does, so watch your balance.
Does it cover calls and SMS?
These are data plans. Calls and texts still run over your normal SIM, or over WhatsApp, FaceTime and similar apps on the eSIM data.
What if I stay longer than planned?
Top up the same eSIM. Fixed plans take more data; daily plans take more days. Both are compatible only with plans for the same country or region, and we only ever show you options that will actually work.
What if it doesn't work when I land?
Email support@bidaiesim.com. Most problems are a setting — data roaming off, or the wrong line picked for mobile data. If we genuinely cannot deliver a working eSIM, you get your money back.
