The Ultimate Cellular Accessories
Along with a mobile handset, the next thing on the to-get list will certainly be some mobile accessories! And it’s absolutely amazing what things they’ve come up with, that’s to be used with a cellular phone, all from the Didn’t Know You Needed It Department. But the most amazing accessory of them all is one that’s simply been overlooked, from the Didn’t Even Know It Was An Accessory Department! Mainly because it isn’t the first thing that would typically one thinks of while looking for cellular accessories – but then again, that’s just the reason for articles like this: to inform you all about it!
The thing is, 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 reverse this programming so that it works with any SIM card, from any carrier. And isn’t that just the best must-have accessory?
Okay, maybe you don’t know very well what a SIM Card is. Well, here’s some technical background, then. There are many kinds of cellular technology in the world, with different 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 in terms of your call itself, with such issues as clarity and coverage. However, should you one day need to switch providers, it can make quite a difference in terms of your convenience, unless you don’t mind throwing away your handset (which you really should recycle instead!).
Now there is a unique electronic serial number for each and every phone, and it is used 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 cellular phones are not directly linked 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 are able to put any SIM card into any GSM phone – or vice-versa – and will work. Therefore, when switching carriers, you just insert the new SIM card, from the new carrier, into your existing phone, without any account set-up or registration on your side!
A lot more than carrying cases or belt clips, unlocking your GSM cellular phone is thus the one true must-have accessory. After all, what exactly is it that cellular accessories do, anyway? They enable you to use your cell phone better somehow, improving your experience of the device. Unlocking your phone is not a physical accessory, however it certainly enhances your experience, making it not just convenient, but possible at all in the first place, to change carriers while keeping the same phone!
