IPhone 5S - GSM or CDMA: how to find out the model

Released in 2013, "old man" was the first smartphone from Apple, equipped with a fingerprint scanner and a 64-bit processor. These characteristics, in conjunction with a fairly productive processor A7 and extremely popular four-inch form factor, allow it to be "in the line" and four years later. Several modifications of it are available, differing in support of the frequencies of the fourth generation. Therefore, when buying it is important to understand what kind of iPhone 5S model you have - GSM or CDMA. How to find the number of the assembly and not make a mistake with the purchase, we will tell.

GSM and CDMA

These abbreviations hide the names of various technologies for the transmission of cellular signals. In general, the difference between the standards is that GSM separates the signal using frequency and time modulation, and CDMA uses only code modulation for the same purpose. As a result, the subscriber in CDMA networks receives a higher quality of communication, and the operator can provide coverage with fewer stations, besides having more flexible tuning.

In Russia, networks of both standards are used. Along with GSM, providing broad coverage, CDMA is actively developing, providing fast data transfer. What is the difference in the models of the iPhone 5S GSM or CDMA, how to find it before buying the phone, so as not to have problems with communication, we will understand in the next section.

Labeling of Apple products

All manufactured products of Apple, which include iPhone modifications, traditionally have an alphanumeric designation, by which you can determine their preferred region of use and frequency range. It looks like this - A0000. Instead of zeros, of course, the digital code of the model is inserted. For iPhone 5S marking is applied in two places:

1. If you buy a phone in the original packaging, in a reliable store or an authorized dealer, then just look at it on the box.
2. If the purchase is made with hands, it is better to inspect the phone itself, not trusting the enclosed package. The second place to mark the model of the iPhone is its back cover.

So, we sorted out the search site. Now let's deal with the iPhone 5S GSM or CDMA. How do you find out the supported frequency range after you find the model code? Just say that the second-generation network will support any model, but after all the smartphone is purchased not only for calls - its operation implies the use of the Internet, without which it will be just an expensive toy.

Frequencies of LTE and models of iPhone 5S

In Russia, four frequency bands are used to create fourth-generation networks . The seventh range is most widely distributed, followed by 3 and 20.

As you can see from the table, the A1457 and A1530 models will work perfectly in domestic networks, but the remaining two can unpleasantly surprise. You can buy them "with caution" only if you know the frequencies used by the cellular operator and do not intend to travel.

Finally

In this article, we told you about the difference between the models of the iPhone 5S GSM or CDMA, how to find out and where to find its number. We hope that the information obtained will help you. Successful acquisitions!
