When you require the Samsung Galaxy M21s unlocking code for free, it is necessary to contact the service provider that has blocked the mobile, they can provide you the SIM network unlock PIN totally for FREE, but you must comply these requirements; you must be the original owner and have paid all pending bills. In these cases, it is very difficult to acquire the free unlocking, so Movical.Net can get you the same unlock code in record time.
The fastest method to obtain the unlocking is ordering in our website, when you put SIM cards from other network providers, the phone will require the unlock code, if you want to get it in a few hours, order it and we will send it to your email.
Please be informed that sometimes the unfreeze MCK code is also needed (when you try to dial the network PIN, Samsung will ask you the - SIM network PIN blocked. Enter SIM network PUK - ) and sometimes it requires the regional code RGCK (just at the moment when you try to use it in another continent). Don't worry, we always provide all the codes.
No, once a Samsung is unlocked, it will be never relocked again, so you can update the firmware without any trouble.
The unlocks that we offer allow you to use all the SIM cards such as Optus, Vodafone from Australia and all over the world.
When a Galaxy M21s does not reject your new SIM card but does not allow you to make calls, it is most likely that the IMEI has been blacklisted. You need to contact with the carrier to solve it.
Some AT&T, Cricket, metroPCS and T-Mobile mobile phones in the USA do not require an unlock code, they are locked with an app pre-installed in the device called Device Unlock, this app is already installed on the mobile phone. Once your order the unlocking, our server authorizes it, simply running the application and pressing the Permanent Unlock button.
A Samsung from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from United States will not prompt the network unlock PIN, these smartphones are blocked by the carrier customized firmware. We can remove the network restriction for these cells, but it must be unlocked through software and sometimes with remote help from one of our technicians.
