Does the vivo X300 support eSIM?
vivo X300 eSIM compatibility
Yes, the vivo X300 supports eSIM—but only on models sold in mainland China. The Chinese variants feature dual-SIM capability: one physical nano-SIM slot plus eSIM. This lets you run two active lines simultaneously, making it convenient for separating work and personal numbers or adding a local data plan when you travel.
If you're looking at the vivo X300 Pro or other variants, the same regional distinction applies: Chinese market models typically include eSIM, while global or international versions may rely on dual physical SIM slots instead. Before you buy, check the official spec sheet for your region to confirm eSIM availability. Retailers sometimes list "dual SIM" without clarifying whether that means dual physical slots or eSIM support, so verify the exact configuration.
Regional and variant differences
The vivo X300 launched primarily for the Chinese market, where eSIM infrastructure is well established with carriers like China Mobile, China Unicom, and China Telecom. Models distributed outside China—including any vivo X300 Pro global version—may omit eSIM functionality entirely in favor of two physical SIM trays. This is common with Chinese smartphone brands that tailor hardware features to local regulatory and carrier requirements.
If you're buying an import or grey-market unit, double-check the model number and region code. A Chinese model will support eSIM and work internationally for data, but you'll need to confirm your home carrier offers eSIM provisioning and that the phone's LTE/5G bands align with your country's networks.
How to set up an eSIM on the vivo X300
Set up an eSIM in Settings
Setting up an eSIM on the vivo X300 takes about a minute once you have your QR code from your carrier or eSIM provider. Make sure you're connected to Wi-Fi before you begin, because the phone needs to reach the carrier's activation server.
- Open Settings and tap Network & Internet or SIM cards & mobile networks (the exact label depends on your software version).
- Select Add mobile plan or eSIM.
- Tap Scan QR code and point your camera at the QR code provided by your carrier or travel eSIM service.
- The vivo X300 will download the eSIM profile. This usually takes 30–60 seconds.
- Once installed, give the line a label—such as "Travel" or "Work"—so you can easily identify it.
- Choose which SIM to use for mobile data, calls, and SMS in the SIM management screen.
Managing dual-SIM settings
After activation, you can control which line handles data, calls, and messages. Head back to SIM cards & mobile networks to set your default line for each function. You can switch mobile data between your physical SIM and eSIM anytime—useful if you want to preserve your home allowance while abroad or use a cheaper local data plan.
Using a travel eSIM on the vivo X300
Stay connected abroad without roaming fees
A travel eSIM is the simplest way to get mobile data when you're overseas. Instead of paying international roaming rates or hunting for a physical SIM card at the airport, you install a data-only eSIM before you fly. Your vivo X300 will connect to a local network at your destination, giving you data for maps, messaging, and email while keeping your primary SIM active for calls and texts.
Most travel eSIM plans activate the moment you land, so there's no counter visit or passport photocopy required. You can browse eSIM plans by destination and data allowance, purchase online, and receive your QR code by email within minutes. Install it at home over Wi-Fi, then toggle it on when you arrive.
Why install before departure
Set up your travel eSIM while you still have reliable internet access. Some airport Wi-Fi networks block the ports needed for eSIM activation, and you don't want to troubleshoot connectivity issues when you've just stepped off a long flight. Pre-installing the profile means you simply switch on mobile data for the eSIM line once you clear customs, and you're online immediately.
Tips & troubleshooting
Turn on data roaming for the eSIM line
Even though your eSIM is a local or regional plan, the vivo X300 may treat it as roaming because it's not your primary carrier. Go to Settings > SIM cards & mobile networks, select your eSIM, and enable Data roaming. This won't trigger roaming charges—you're using the eSIM provider's included data—but the phone needs the toggle on to connect.
Keep your home SIM for calls and two-factor codes
Leave your physical SIM active so you can receive voice calls and SMS verification codes on your regular number. Set the eSIM as your data line and your physical SIM for calls and messages. That way, banking apps and services that send one-time passwords will still reach you without extra cost.
Fix an eSIM that won't activate
If the QR code won't scan, check that your camera lens is clean and you're holding the phone steady about 15–20 centimeters from the screen. Alternatively, many carriers let you enter the activation code manually: look for Enter code manually or Activation code in the add-eSIM menu and type in the SM-DP+ address and confirmation code provided.
If the profile downloads but won't activate, restart the vivo X300 and make sure you have a strong Wi-Fi signal. Activation servers time out on slow or unstable connections. Still stuck? Visit our eSIM setup help for carrier-specific guides and live support.
Verify eSIM compatibility before you buy
If you're considering a vivo X300 and eSIM capability is a must-have, confirm the model and region before purchase. Chinese models support eSIM; global or Indian market variants often do not. You can always check another device's eSIM compatibility if you're weighing alternatives like the vivo X300 Pro or other recent flagships.
