Phone and Tablet Unlocks

Tech Guru provides professional unlocking services for your cellphone to make it work in Greek mobile networks with Greek sim cards. We can also recover your forgotten Google account in your android phone or unlock your screen lock in smartphones and tablets (Google FRP, Mi Account etc).

Many phones bought from a foreign country are locked from the initial provider to work only with their sim cards, e.g. O2 UK, T-Mobile USA etc, making them useless phones outside the initial country. These phones usually ask for "Network Unlock Pin" or show the "Invalid SIM" message. We are able to unlock these barriers for you and make the phone work worldwide with any SIM card.

We can unlock anyphone brand like Samsung, Xiaomi, Huawei/Honor, iPhone, LG, Alcatel, Sony Ericsson/Sony Xperia, HTC, Lenovo, Motorola, Blackberry, ZTE, Microsoft/Nokia, Vodafone, OPPO, Cubot, Vivo and from all over the world.

Unlocks are done via your devices' IMEI number or sometimes using a cable with specialized software. There is no need to use methods like Jailbreak, Custom Android ROMs etc. If you cannot see your IMEI number or it is corrupted, we can fix it for you.

We have the best specialized equipment for phone service (service boxes) which can work on Android devices with processors Qualcomm, Exynos, Mediatek (MTK), Spreadtrum and many other.

As for iPhones, we have access to the best unlocking servers and online services to unlock any iPhone via IMEI with a 99% success even if the phone is blacklisted at the initial carrier. That is the reason why other repair centers and companies trust us for those services and we receive phones from all over Greece via courrier.
