In case you’ve bought Galaxy Note 3 device from a carrier, then it means that it is locked on that particular network. If you want to use it with any other carrier/ network, then you will be forced to unlock the Galaxy Note 3 SIM for it to work.
Usually a SIM for Note 3 is locked because major carriers don’t want consumers to use the purchased devices with other carriers or networks.
This guide will teach you how to successfully unlock SIM from other carriers and use it with the same Samsung Galaxy Note 3 phablet. In this post you will find two alternative methods, one will tell you how to SIM Unlock the Note 3 for free, while the other will require you to buy an unlock code from a website specialized in unlocked SIM for smartphones worldwide.
Please note that if you do manage to SIM Unlock your Galaxy Note 3, then this won’t necessarily mean that it will work for all networks or carriers. That is because usually carriers are using different GSM bands and not all are compatible with your Note 3 model.
