Request an Unlock directly to Tesco

How to: You'll need to submit an online request using Tesco Mobile's official unlock module and wait for them to send your unlocking instructions via email or text message (if eligible).
Timeframe: Up to 7 working days Tesco normally takes up to 7 working days to unlock any pay-as-you-go or pay monthly phone, but it can be more if there's an issue with your account or they need to contact your phone manufacturer (Samsung, Apple, etc.).
Price: Free Unlocking a phone directly with Tesco Mobile is completely free of charge unless you owe them money, like, for example, if your account has past due fees and you need to bring it up to date.
Requirements: You must be the account holder, and the phone must be fully paid off or out of contract. Also, the device can't be blacklisted and it must be linked to a SIM card with an active number.
Safety: 100% Safe Unlocking a handset directly with its original network provider is always completely safe and is, in fact, the official alternative that all users should consider before anything else.

Hire an Expert Unlock Technician

How to: All you need to do is visit a certified phone repair shop or mobile technician that offers unlocking services in your area, and take your device with you for them to check it out.
Timeframe: 2 hours to days This depends on the person who's fixing your phone, so it can be two hours or it can take days, but normally, you need to leave the device with them until they tell you it's ready.
Price: £20–£50 Taking your phone to a repair shop can cost around £20–£50, depending on the phone model and your exact location (it's a little more expensive if we're talking about an Apple device).
Requirements: The device must not be blacklisted or reported as lost/stolen, and also, you should know technicians often need the phone IMEI and sometimes proof of purchase.
Safety: Safe This method is safe as long as you choose a reliable and certified repair shop, which is normally more expensive, but at least you have the peace of mind that they won't brick your phone.

Use a Bypass App (APK or IPA File)

How to: Download and install a third-party carrier bypass app (this is only for certain Android or jailbroken iOS devices). Keep in mind that these programs don't truly unlock your handset but just bypass the lock.
Timeframe: Instant These third-party apps work as soon as you install the program on the device and give them the permissions they need, of course, only if the app works on your specific phone model.
Price: ÂŁ15/month Most apps work with monthly or yearly subscriptions, so you need to make recurrent payments of more or less ÂŁ15, but it all depends on the program you're installing.
Requirements: These apps may require root or jailbreak and are not compatible with most iPhones because Apple has very important security layers that don't let them work.
Safety: Not Recommended Bypass apps are not recommended because they're too invasive (they need to be downloaded and installed from untrusted sources) and can come with malware.

Root/Jailbreak the Locked Device

How to: You just need to either use advanced tools or hire someone to root (Android) or jailbreak (iOS) your device to bypass its network restrictions.
Timeframe: 1–2 hours This takes around 1–2 hours, depending on the tool used and whether you actually know how to perform this complicated procedure.
Price: Free or ÂŁ30 This doesn't have any cost if you perform the root/jailbreak yourself, but if you pay a technician to do it, they might charge you approximately ÂŁ30.
Requirements: Technical knowledge is required because the procedure is very complicated, and you can easily brick the phone if done incorrectly. Keep in mind that rooting/jailbreaking is not legal in some regions!
Safety: Not Safe Rooting or jailbreaking a locked phone is not safe at all. You will void your device warranty, expose your handset to cyberattacks, and most likely brick your phone because they're not meant to support these types of modifications.
