Why to unlock cell phone ? Do you really

want it!!

Unlocking Won’t Make Phones Completely PortableFirst, it’s important to bear in mind that phones won’t always be capable of working on another carrier even after they’re unlocked. For example, in the USA, AT&T and T-Mobile use the GSM wireless standard, while Verizon and Sprint use the CDMA wireless standard. These are incompatible with each other, which means that you can’t unlock a CDMA phone purchased on Verizon and take it to AT&T’s GSM network, or vice versa.

CDMA is also a more restrictive type of network — while you can unlock an AT&T phone and take it to T-Mobile, you can’t unlock a Verizon phone and take it to Sprint, as Sprint’s CDMA network will reject the phone.

Luckily, most of the world has chosen the less-restrictive GSM standard. Before you consider unlocking a phone and taking it to another carrier, ensure that your phone will actually be capable of functioning on that carrier’s network.

Phone Locking Explained

For example, let’s say you walk into AT&T and pick up any smartphone on contract. That phone will then function on AT&T’s network, but if you try to place a T-Mobile SIM card into the phone and switch to T-Mobile’s network, the phone will reject the T-Mobile SIM card. There’s no legitimate technical reason for this — it’s compatible — but the AT&T phone is “locked” to AT&T’s network and will only accept AT&T SIM cards.

This would also get in your way if you were travelling and wished to use a local carrier in the country you were visiting rather than paying expensive roaming fees — your locked phone would reject anything but an AT&T SIM card.

Why Are Phones Locked?Cellular carriers argue that phone locking is a necessary part of their business. By locking phones they sell on contract, they’re able to keep customers on their network so they’ll continue paying their monthly bills. Remember, phones aren’t actually worth their on contract prices — they’re subsidized. No phone is actually “free” and the latest iPhone actually costs more than $199 — so the carrier needs to recover the cost of the on-contract phone over the lifetime of the contract. If consumers were able to take their phones to other networks, carriers argue that they would have difficulty recovering the price of the phone and their business model would take a hit.
