eSIM technology has made mobile connectivity more convenient, especially for frequent travelers and digital nomads. Whether you're using eSIM Vietnam for a local network or an international roaming plan, you may wonder: what happens if you delete esim? Does it permanently remove your number? Can you restore it later?
Before you delete your eSIM, it's essential to understand the consequences and what steps you should take to avoid losing access to your mobile network.
How eSIM Works in Vietnam
An eSIM (embedded SIM) is a digital version of a physical SIM card that allows you to activate a mobile plan without inserting a physical chip. In Vietnam, major carriers like Viettel, Vinaphone, and Mobifone provide eSIM Vietnam services, making it easy for users to switch networks or set up multiple phone numbers on a single device.
eSIM offers several advantages, such as:
Instant activation without visiting a store.
Dual SIM support, allowing you to use one eSIM and one physical SIM.
Easy switching between different carriers or plans.
Ideal for tourists, business travelers, and remote workers.
However, if you delete your eSIM, you may lose these benefits. Here’s what you need to know before making that decision.
What Happens If You Delete eSIM?
1. Your Network Connection Is Immediately Lost
Once you delete your eSIM, your phone will no longer be connected to the mobile network. This means:
No calling or texting.
No mobile data unless you connect to Wi-Fi.
No access to your carrier’s services, including voicemail or mobile payments.
For those relying on eSIM Vietnam for daily communication, deleting it without a backup plan can be a big problem.
2. You Might Not Be Able to Restore It
Unlike a physical SIM that you can remove and reinsert, a deleted eSIM is permanently erased from your phone. Some carriers allow you to reinstall the same eSIM using the original QR code, but others require you to request a new one.
If you're on a prepaid eSIM Vietnam plan, deleting your eSIM could mean losing your remaining balance or data package.
3. You May Have to Pay for a New eSIM
Many mobile carriers charge for eSIM activation, especially if you need a replacement. If you delete your eSIM and later realize you still need it, you might have to purchase a new plan or pay a reactivation fee.
For travelers using eSIM Vietnam, this means you may lose your prepaid travel plan and have to buy a new one.
4. It Affects Dual SIM Functionality
If you use dual SIM mode (one eSIM and one physical SIM), deleting your eSIM will disable this feature. Many people use dual SIM for separating work and personal numbers, so removing eSIM without a backup option could disrupt your phone setup.
5. You’ll Need to Contact Customer Support for Recovery
If you delete your eSIM by accident and your carrier doesn’t allow reinstallation, you’ll have to reach out to their support team to request a new activation code. This process may take time and could be an inconvenience if you’re traveling or don’t have access to another number.
When Should You Delete Your eSIM?
You should only delete your eSIM if:
✅ You are switching to a new eSIM and have already activated the replacement.
✅ You no longer need the number or service associated with the eSIM.
✅ You have confirmed with your carrier that you can reinstall the eSIM later.
If you’re unsure whether you’ll need your eSIM again, it’s better to keep it active until you’re ready to switch to another plan.
How to Delete eSIM the Right Way
If you’ve decided to delete your eSIM, follow these steps carefully:
Check Your Carrier’s Policy – Find out if your provider allows you to reinstall the same eSIM or if you’ll need a new activation code.
Back Up Your Contacts and Messages – If your eSIM number is linked to any important contacts or SMS-based services, save them before deletion.
Go to Your Phone’s Settings:
For iPhone: Go to Settings > Cellular > Your eSIM Plan > Remove eSIM.
For Android: Go to Settings > Network & Internet > SIMs > Select eSIM > Delete.
Confirm Deletion – Once deleted, your device will lose its mobile network connection.
Set Up a New eSIM (If Needed) – If switching to another eSIM, scan the new QR code provided by your carrier.
Final Thoughts
So, what happens if you delete eSIM? In short, you immediately lose network access, and depending on your carrier, you may not be able to restore it without paying for a new activation.
For users relying on esim vietnam, this could mean losing their prepaid plan, affecting dual SIM functionality, or needing to contact customer support for a new activation.
Before deleting your eSIM, make sure you understand your carrier’s policies and have a backup plan in place. If you’re switching to another carrier, it’s best to activate your new eSIM before removing the old one.
