How to Unlock Tesco Mobile: Free Unlock Code & Trusted IMEI Method

“After I bought my new phone I started to think it has been locked to the Tesco Mobile network. How can I check if this is true and how do I unlock it from Tesco Mobile?”

Carrier locks are incredibly limiting to anyone who purchases a second-hand phone or who wants to switch to a network with cheaper plans. This is because with a carrier lock, you can only use the phone on a specific network. In this case, encountering a Tesco Mobile lock will need to be remedied by learning how to unlock Tesco Mobile.

By reading this article you’ll learn how to check if your phone has actually been carrier locked, as well as what methods there are to unlock it.

Part 1. How to Know if Your Phone is Locked to Tesco Mobile?

First thing’s first: before unlocking a phone, we need to make sure it’s locked. If it turns out there isn’t actually a lock in place, then you can avoid this process altogether. To check if a mobile phone is locked to a carrier, follow these steps.

Step 1. Remove the current Tesco Mobile SIM card from your phone.

Step 2. Insert a SIM card from a different carrier (e.g. EE, T-Mobile, O2, etc).

Step 3. Check if your phone connects to the different carrier network.

If the phone does connect then there isn’t a carrier lock, but if it refuses to connect to any network that isn’t Tesco Mobile, a carrier lock is active. If you don’t have a different SIM card, just check it without SIM card.

This will likely confirm that there is a carrier lock on your phone. In that case, the next thing to do is look into Tesco Mobile unlock solutions.

Part 2. How to Unlock Your Tesco Mobile Phone?

Although there are lots of different solutions to unlock Tesco Mobile phone, we’ve handpicked the 2 methods we believe to be the most effective and worth focusing on.

Before unlocking, you need to know the blacklist status of your phone. If it’s blacklisted, none of the methods work for you. The most accurate way to check the blacklist status is to use WipeLock IMEI Checker.

If the blacklist status is “Clean,” you can use either of the methods below to unlock your phone.

Method 1. Unlock Tesco Mobile with an Unlock Code (7 Days)

First of all, you can take the direct approach of contacting Tesco Mobile. By doing this, you can request an unlock code which you can then use to remove the carrier lock yourself. You will be charged for this service and how much you pay will differ depending on the Tesco Mobile plan that the SIM card has.

  • Bill Pay Plan. With this type of plan, you won’t have to make a payment, although you still have to meet the terms of your phone contract.
  • Pay As You Go. You may unlock your phone if it has been connected to the Tesco Mobile network for a minimum of 9 months. Otherwise, you are required to have a €150 balance.
  • Capped Plan. Similar to PAYG plans, you must have had the phone connected to the Tesco Mobile network for at least 9 months or have paid €150 in total.

Steps to Get Free Tesco Mobile Unlock Code

Prices for a Tesco Mobile unlock are clearly very steep, so it’s not optimal. Nonetheless, if you’re on a Bill Pay Plan, here’s how you can proceed with unlocking this way:

Step 1. Go to the Tesco Mobile support page. And click on the the ‘Send an email’ section.

Step 2. Offer all the information they required, including your name, phone number, email address. Select your phone plan.

Step 3. Then select “Request Phone Codes” > “Request phone unlock code”

Step 4. Type the phone’s IMEI number which can be found by dialing *#06#.

Step 5. Leave your message as detailed as possible. And click on the “Send Message” button.

Step 6. After receiving your unlock request, Tesco will contact you after 3 – 21 days with unlock code and further instructions via text.

Although you’ll be waiting as long as 21 working days to unlock Tesco Mobile, it gets the job done.
