eSIM technology has made mobile connectivity easier than ever, eliminating the need for physical SIM cards. However, if you’re using eSIM Vietnam services or considering deleting your eSIM for any reason, you might be wondering: what happens if you delete esim? Will you lose your number? Can you restore it later? This guide covers everything you need to know before making that decision.
What Is eSIM and Why Is It Popular in Vietnam?
An eSIM (embedded SIM) is a digital SIM that lets you activate a cellular plan without a physical SIM card. Unlike traditional SIM cards, eSIMs are built into your device and can be activated by scanning a QR code provided by your carrier.
In Vietnam, many mobile providers, including Viettel, Vinaphone, and Mobifone, offer eSIM Vietnam plans, making it easy for travelers, digital nomads, and locals to switch networks without needing to visit a store. eSIMs are especially useful for those who need multiple numbers, frequent travelers, or people looking for a hassle-free mobile experience.
What Happens If You Delete eSIM?
Deleting your eSIM might seem like a simple action, but it comes with consequences. Here’s what you need to know before removing it from your phone.
1. Your Mobile Network Connection Will Be Lost
Once you delete your eSIM, your phone will immediately lose connection to the network. This means you won’t be able to make calls, send texts, or use mobile data unless you have another SIM or eSIM profile active.
For users relying on eSIM Vietnam for internet access, this can be a major issue, especially if there’s no Wi-Fi available.
2. Reinstalling eSIM Isn’t Always Possible
Many mobile carriers issue a one-time QR code for eSIM activation. If you delete your eSIM, some providers allow you to reinstall it using the same QR code, while others require you to request a new one.
If you're using eSIM Vietnam from a prepaid provider, deleting it might mean you have to buy a new plan altogether. Before removing your eSIM, check with your carrier to see if you can restore it later.
3. You Might Need to Pay for a New eSIM
Depending on your carrier, deleting your eSIM could result in additional costs. Some providers treat eSIM deletion as a cancellation, meaning you may need to pay for a new plan or reactivation.
This is particularly important for international travelers using eSIM Vietnam services—deleting your eSIM could mean losing your prepaid data plan and needing to repurchase one.
4. Dual SIM Functionality Will Be Affected
If you use dual SIM mode (one physical SIM + one eSIM), deleting your eSIM will disable this feature. This is important if you rely on having two numbers—one for work and one for personal use.
Before deleting your eSIM, make sure you have an alternative way to stay connected if you need dual SIM functionality.
5. You May Need to Contact Customer Support for Recovery
Unlike physical SIM cards that you can reinsert, a deleted eSIM can’t be recovered easily. If your carrier doesn’t allow you to reuse the same QR code, you’ll have to contact their support team to request a new eSIM activation.
For those using eSIM Vietnam, this can be an inconvenience, especially if you’re traveling and unable to visit a local store.
Should You Delete Your eSIM?
Before deleting your eSIM, ask yourself these questions:
Do I have an alternative way to stay connected? (Another SIM, Wi-Fi access, etc.)
Can I reinstall the eSIM later? (Check with your carrier)
Will I have to pay for a new activation?
Do I need dual SIM functionality?
If you’re unsure, it’s best to avoid deleting your eSIM until you confirm your carrier’s policies.
How to Delete eSIM (If Necessary)
If you’ve decided to delete your eSIM, follow these steps:
Check Your Carrier’s Policy – Some carriers allow reinstallation, while others don’t. Verify before proceeding.
Backup Your Information – Save important contacts and messages linked to your eSIM number.
Go to Phone Settings:
iPhone: Go to Settings > Cellular > Your eSIM Plan > Remove eSIM.
Android: Go to Settings > Network & Internet > SIMs > Your eSIM > Delete.
Confirm Deletion – Once deleted, the eSIM profile is permanently removed.
Set Up a New eSIM (If Needed) – If you need a new eSIM, contact your provider for a new activation code.
Final Thoughts
So, what happens if you delete eSIM? In short, you lose your network access, and restoring it may not be easy. For users relying on esim vietnam, this can be a major inconvenience, as you may need to repurchase a plan or request a new activation code.
Before deleting your eSIM, check with your carrier to understand the consequences. If you need to switch networks, consider keeping your current eSIM active until you’ve successfully activated a new one.
