When to Unlock Phone

Unlocking your smartphone is legal now so there’s no reason why you shouldn’t unlock your phone?
Unlocking your smartphone provides you more power over your device. So if you can get three major reasons why you should take advantage of unlocking:
To use your phone internationally:
To attract clients, carriers typically subsidize the purchase cost of a device when a user signs up for a new contract and lock the subsidized phone to their service. For example, if you purchase an iPhone8 from any shop without a contract, the device would cost you higher than the actual price. If you sign up for a contract, then they will sell you the phone at a less price, but the device will be locked by the carrier and will only work on its network.
That also means that if you travel internationally, you can’t just switch out the AT&T SIM card for a local one it won’t work. Instead, you’ll have to pay AT&T to use the phone internationally through the carrier’s partners. So, it’s better to unlock your phone to use it internationally.
To increase your phones resale value:
By unlocking your phone you can easily increase the value of your phone. Eventually, we all sell or give away our old smartphones, but it inherently has less value if it’s stuck on a specific wireless provider. If you want to get the most value from selling that old device, or if you want to give it to someone who isn’t necessarily on the same carrier as you are, then unlocking your phone is the best way to get the full value of your phone.
To switch carriers:
If you are sick of your present carrier and want to switch it then probably you prefer buying a new SIM card. But because oh the contracts and locking, it’s not so easy. If you want to switch service providers for any reason, such as poor cell coverage in your area, then you’ll need to buy a new device if your phone is locked. An unlocked phone, however, can be used on your new carrier’s network, as long as the device itself is supported.
