What exactly is an eSIM?

eSIM is short for Embedded SIM — a digital chip built into the phone. You load a carrier profile onto it instead of inserting a plastic SIM. Most recent iPhones, Samsung phones, and Pixels support it.

What is Kovitel eSIM?

Kovitel eSIM is provided directly by Viettel, Vietnam's strongest mobile network. You get local 5G priority access — not a throttled roaming reseller — with coverage from city centres to mountains and islands.

Which devices work with Kovitel eSIM?

Most flagship phones from 2019 onwards. Confirm your model on the compatibility list, and check that the phone is carrier-unlocked.

How do I order an eSIM?

1. Go to kovitel.com. 2. Choose the 7, 15, or 30-day plan and add it to cart. 3. Check out and pay. 4. Your QR code and setup email arrive in about 5–10 minutes.

Do I need to provide ID to buy an eSIM?

No. No eKYC, no passport upload. Pick a plan, pay, and we send the QR to your email.

Is hotspot / tethering supported?

Yes. You can share the Viettel eSIM connection with other devices.

How do I check if my iPhone is eSIM-ready and unlocked?

1. Open Settings → General → About. 2. Carrier Lock should read 'No SIM restrictions'. 3. If you see a Digital SIM / eSIM IMEI, the iPhone supports eSIM. You can also dial *#06# and look for an EID.

How do I check if my Android phone supports eSIM?

Samsung: Settings → About phone → Status → IMEI information. Look for IMEI (eSIM). Other Android: dial *#06#. An EID means the phone supports eSIM.

Should I buy my eSIM before travelling or after I arrive?

Buy before you leave so setup is ready. The plan validity only begins when the eSIM connects to the Viettel network in Vietnam, not on purchase.

When does the data plan start?

Validity starts the moment the eSIM connects to a mobile network in Vietnam, not when you scan the QR code.

I typed the wrong email address at checkout. How do I update it?

Message support via WhatsApp or email with your order number or payment receipt. We will verify and re-send the QR code immediately.

When should I install my eSIM?

Install about one day before you travel on stable Wi-Fi. Do not switch on data roaming for the Kovitel line until you have landed in Vietnam.

How do I install a Kovitel eSIM?

Scan the QR code in the email, or enter the SM-DP+ address and code manually. Full walkthroughs for iPhone, Samsung, and Pixel are on the installation guide.

How do I configure the APN for my eSIM?

Most Kovitel profiles set APN automatically. If data does not start: iPhone: Settings → Cellular → eSIM line → Cellular Data Network (enter APN from email). Samsung: Settings → Connections → Mobile networks → Access Point Names. Pixel: Settings → Network & internet → SIMs → eSIM → Access Point Names.

What does 'Invalid Activation Code' mean?

Usually a blurry or cropped QR, or the camera cannot read it. Clean the lens and scan again, or use manual entry with the SM-DP+ address and activation code from the confirmation email.

What does 'Data Plan Cannot Be Added' mean?

That QR code has already been used on this phone or another. Check if the profile is already installed in Cellular settings or contact Kovitel support.

What does 'Cellular Plans from This Carrier Cannot Be Added' mean?

The phone is carrier-locked. eSIM requires an unlocked GSM phone. Contact your original carrier to unlock your handset.

What does 'Unable to Complete Cellular Plan Change' mean?

The phone may have reached its maximum stored eSIM limit (delete unused profiles), or Wi-Fi was interrupted during installation. Re-connect to stable Wi-Fi and retry.
