iPad + Vietnam eSIM: can you tether a laptop?

A local Vietnam eSIM on an iPad cellular model can share internet to a laptop via Personal Hotspot in most cases. Carriers like Viettel, Vinaphone, and Mobifone generally allow tethering on their standard data plans. Some reseller eSIMs (e.g., certain Airalo plans) may restrict hotspot usage, but native Vietnamese carriers rarely block it.

The Viettel and Vinaphone eSIMs we sell allow tethering by default – no extra configuration needed. The Skyfi (Mobifone) plan also supports it. Tethering speed depends on 4G/5G signal in your location; typical speeds are enough for email, browsing, and video calls. If you plan to stream 4K video or run large downloads, keep in mind that your daily data cap applies to all tethered devices.

Viettel publicly states that Personal Hotspot is allowed on all data plans, including eSIM, with no extra fee. Vinaphone follows a similar policy – tethering counts against your data allowance (e.g., 5GB per day on our 10-day plan). Mobifone’s current 7GB/day plan we offer permits tethering, although some older Mobifone plans did block hotspot. We confirm our product supports it.

Reseller eSIMs from platforms like Airalo, HolaFly, or Ubigi may block tethering entirely or limit it to one connected device. Always check their fine print before buying. With a direct local carrier eSIM, you avoid that uncertainty.

Your iPad must be a cellular model (Wi-Fi + Cellular) with eSIM capability. According to Apple, the following models support eSIM: iPad Pro 11-inch (1st generation and later), iPad Pro 12.9-inch (3rd generation and later), iPad Air (3rd generation and later), iPad (7th generation and later), and iPad mini (5th generation and later). It must also be unlocked by your home carrier – if it’s locked to, say, AT&T or SoftBank, a foreign eSIM won’t activate.

Your iPad needs iOS 12.1 or newer for basic eSIM support, and iPadOS 13+ for Personal Hotspot over eSIM. Mainland China-purchased iPad cellular models do have eSIM but may be limited to local carriers (China Mobile/China Unicom); in our experience, foreign eSIMs often work, but we recommend checking with the seller. Note that Chinese iPhones lack eSIM entirely. If your iPad shows ‘Personal Hotspot’ grayed out after installing the eSIM, check carrier APN settings or try resetting network settings.

Step 1: Install the Vietnam eSIM (via QR code) on your iPad while on Wi-Fi – either before departure or upon arrival. Step 2: Go to Settings > Cellular > Cellular Data and select the Vietnam eSIM line. Step 3: Tap ‘Personal Hotspot’ and toggle on ‘Allow Others to Join’.

Step 4: Connect your laptop via Wi-Fi – scan the QR code shown on the iPad or enter the password displayed. Step 5: Verify the connection: your laptop should receive an IPv4 address via NAT. If the Personal Hotspot option does not appear, your carrier may block it; contact our support for APN guidance.

If tethering doesn’t work, first ensure the eSIM has an active data connection – check that Cellular Data is toggled on and you see a signal. Reset network settings on the iPad: Settings > General > Transfer or Reset > Reset > Reset Network Settings (this will erase saved Wi-Fi passwords and Bluetooth pairings).

Try connecting a different device – some laptops have Wi-Fi band compatibility issues. If still stuck, manually enter APN settings: for Viettel, set APN to ‘internet’ with blank username/password; for Vinaphone, use ‘m-wap’ or ‘internet’.
