Apple/iPhone Carrier Check

- If you bought your iPhone under an installment plan or monthly contract from carriers such as T-Mobile, AT&T, Verizon, Vodafone, or similar, your phone might be network-locked. as carriers often lock phones until they are fully paid off to prevent fraud and promote customer loyalty.
- To check if your iPhone is locked, go to Settings > General > About and look for Carrier Lock; if it says "SIM locked," you'll need to request an unlock from your carrier.
If your phone is locked you can not use esim and other mobile networks, Please contact your mobile carrier to unlock your phone

Yes, of course, you can. But please keep in mind the following things: Set your SIM card for phone calls and SMS, and Vietnam eSIM for mobile data on your phone. Do not Turn on Auto data switching mode on your phone (if any) to avoid data roaming charge on your primary SIM card. International roaming charges might be applied for making phone calls and sending SMS. So, it is highly recommended to keep your primary phone number active only when you need to receive calls and SMS when you are in Vietnam. Otherwise, make full use of our esim's unlimited data to contact your friends, family members via Apps like Whatsapp, etc.
Here are the main reasons this happens:
1. Restricted airport Wi-Fi
Many airport public networks block certain services (like QR code activation servers or carrier connections), which can prevent eSIM installation.
2. Unstable connection
Free Wi-Fi at airports is often slow or overloaded, causing the eSIM download to fail.
3. Security limitations
Some eSIM activation requires a secure and stable connection. Public Wi-Fi may not meet those requirements.
4. VPN or firewall issues
If you're using a VPN or if the network has a firewall, it can interfere with the eSIM activation process.
How to fix it:
Switch to a different Wi-Fi network (hotel, café, etc.)
Use mobile data from another SIM
Turn off VPN if enabled
Try again in an area with stronger signal
