Installation guide
Install your Best Global eSIM in under a minute
Scan a QR code with your phone's camera, tap a couple of buttons, and you're set. No new app, no SIM swap — your home line stays put and the Best Global eSIM sits beside it as a second cellular line.
Scan the QR code
Fastest path. Open the email on a second screen, point your phone's camera at it. Your phone offers to add the eSIM in one tap.
An eSIM-ready phone
Every iPhone from XR (2018) onward, every recent Pixel and Galaxy flagship, and most modern OnePlus / Motorola devices.
Your QR email
We sent it the moment your payment cleared. Open it on a computer, tablet, or print — anything other than the phone you're installing on.
Wi-Fi handy
Install before you fly. The eSIM downloads over Wi-Fi during setup; validity only counts once you use data in the destination.
Two ways to install
Scan the QR code
Fastest path. Open the email on a second screen, point your phone's camera at it. Your phone offers to add the eSIM in one tap.
Type the code manually
When the QR isn't reachable, every step below has an "enter manually" option. The activation string is in the same email under the QR image.
iPhone (iOS 16 and later)
Same flow for every iPhone from the XR onward. Make sure you're on Wi-Fi and have your QR email open on another screen.
SIMs
Cellular data
- 1
Open Settings, tap Cellular
On dual-SIM iPhones the section is called Cellular; some regions call it Mobile Service or Mobile Data — same place.
- 2
Tap Add eSIM
Scroll past your existing SIM, find the Add eSIM (or Add Cellular Plan) row. You'll be offered to transfer from a nearby device — pick Use QR Code instead.
- 3
Scan the QR code from your email
Hold the phone over the QR image on your computer or tablet. The frame snaps green when it reads. If the camera can't see it, tap Enter Details Manually and copy the SM-DP+ address + activation code from the email.
- 4
Confirm the new plan
iOS shows the plan name (Best Global eSIM · Travel data) and asks you to continue. Tap Continue through the next two screens — the defaults are fine.
- 5
Label the line
Pick Travel (or any label you like) so you can tell the two lines apart in the dialer. This is purely cosmetic — nothing breaks if you skip it.
- 6
Set Best Global eSIM as your data line
On the next screen, choose your Best Global eSIM line for Cellular Data. Keep your primary line for calls and SMS so your home number still rings. That's it — you're installed.
Android (Samsung, Pixel, OnePlus, others)
Menu paths vary slightly by manufacturer. The labels below match Samsung One UI 6+ and Pixel — on Xiaomi / OnePlus look for SIM card manager or Mobile network under Connections.
SIM cards
Preferred SIM
- 1
Open Settings, tap Connections
On Pixel it's called Network & internet. Same place — the row that holds Wi-Fi, Bluetooth, and SIMs.
- 2
Open SIM manager
Samsung calls it SIM manager, Pixel calls it SIMs, others sometimes Mobile network. Whichever it's called, that's the screen where every line on the phone lives.
- 3
Tap Add eSIM
If your phone already has an eSIM slot occupied, you'll need to either reset it or move it to free a slot — most phones support several but a few are limited to one active eSIM at a time.
- 4
Scan the QR code
Same as on iPhone — point the camera at the QR image in your email. If scanning fails, tap Enter activation code manually and paste the string from the email.
- 5
Switch mobile data to Best Global eSIM
Once the eSIM is added, open Mobile data in SIM manager and pick the Best Global eSIM line. Leave calls and SMS pointing at your home SIM so your number keeps working.
Troubleshooting
I scanned the QR but my phone said "can't add eSIM"
Almost always a Wi-Fi issue — the install needs an internet connection to fetch the eSIM profile. Switch to a stable Wi-Fi network and try again. If you're already on Wi-Fi, restart the phone and re-scan; that resets the eSIM provisioning state.
The QR code won't scan from my screen
Increase your computer's brightness, make the QR larger in the email, and move your phone 15–20 cm away from the screen. If it still won't scan, every step has a manual path — open the email, copy the SM-DP+ address and activation code, and paste them in.
The eSIM installed but I have no service
Check three things, in order: (1) is data roaming ON for the Best Global eSIM line? (2) is Mobile Data set to the Best Global eSIM line? (3) are you in the destination country yet — validity only starts on first in-country data use. If all three check out, toggle airplane mode for 30 seconds and let the phone re-attach.
I installed twice and now I have two eSIMs from Best Global eSIM
Open Cellular (iPhone) or SIM manager (Android) and remove the duplicate. Each Best Global eSIM has its own ICCID printed in the email — the older one is the duplicate. Removing the wrong one won't affect billing; just re-install the correct one from the same email.
I'm running out of high-speed data faster than expected
If you're on an unlimited day-pass plan, every day you get a fresh high-speed allotment that resets at midnight UTC — and the slower throttled speed after the cap is still usable for messaging, maps, and email. Heavy streaming and tethering eat through the daily cap fast; switching to a 2 GB/day or 3 GB/day plan typically fixes it.
