Having a mobile handset, the next matter on the to-get list will certainly be some mobile accessories! And it’s absolutely astonishing what stuff they’ve come up with, that’s to be used with a cell phone, all from the Didn’t Know You Needed It Department. But the most wonderful accessory of them all is but one that’s simply been overlooked, in the Didn’t Even Know It Was An Accessory Department! Simply because it isn’t the first thing that would normally come to mind when looking for cellular accessories – but then again, that’s just the reason for articles like this: to tell you all about it!
You see, some wireless providers choose to “lock” their phones, unfortunately, so that they can’t work with SIM cards from another provider. Unlocking your phone means to change this programming so that it will work with any SIM card, from any carrier. And isn’t that just the greatest must-have accessory?
Okay, maybe you don’t know what a SIM Card is. Well, here’s some technical background, then. There are lots of types of cellular technology in the world, with various protocols and standards, and one of them is called GSM. It’s not as common in the United States as another called CDMA, but most countries use GSM primarily, if not outright exclusively. Now everything else being equal, it shouldn’t matter much with regards to your call itself, with such issues as clarity and coverage. However, in the event you one day want to switch providers, it could make a significant difference with regards to your convenience, unless you don’t mind throwing out your handset (which you really should recycle instead!).
Now there is a distinctive electronic serial number for each and every phone, and it is utilized by your carrier to distinguish your account. Through this serial number, the carrier sees that a certain phone is yours and is thus able to route calls to you using this method. But GSM mobile phones aren’t directly connected to their owners, where the phone itself does not contain the serial number. Instead, each GSM handset contains a removable Subscriber Information Module card, or SIM card, that holds the serial number. This implies that you can put any SIM card into any GSM phone – or vice-versa – and will work. Therefore, when switching carriers, you merely insert the new SIM card, from the new carrier, into your existing phone, with no account set-up or registration on your side!
A lot more than carrying cases or belt clips, unlocking your GSM cell phone is thus the one true must-have accessory. After all, what exactly is it that cellular accessories do, anyway? They help you use your cellular phone better somehow, enhancing your experience of the device. Unlocking your phone isn’t a physical accessory, but it definitely enhances your experience, which makes it not just convenient, but possible at all in the first place, to switch carriers while keeping the same phone!
