Why gsm is preferred over cdma




















The call quality of both nationwide networks heavily depends on the network coverage. Furthermore, the GSM network can transmit voice and data simultaneously. On the other hand, not all CDMA phones can transmit voice and data at the same time.

GSM uses ore dedicated network towers plus it enables worldwide roaming. In contrary, CDMA network towers are more widespread, has a higher coverage but only limited roaming options. What is GSM? So watching a video, downloading apps or just browsing on a website is faster. It works better in real time. You will never notice pauses in voice calls or in online games. Just a few users know that 4G will drop the network congestion so the data will move faster from the client to the server and back making our connection more stable.

In this way, a lot of users can be connected at the same time in the same zone. Disadvantages of 4G You can only use 4G if your cell phone is compatible with this technology.

There are some areas where 4G is still not available nowadays. Despite that 4G has an excellent speed connection; it does not exceed the optical fiber. However, it is still the best way to browse on the internet using your mobile phone. No matter how fast 4G mobile internet is, it still has a data limit in most cases. Users can consume contents faster but not a greater amount.

What is LTE? What is 5G? The Quality of the Call The call quality of both nationwide networks heavily depends on the network coverage. Network Coverage GSM uses ore dedicated network towers plus it enables worldwide roaming.

Published on 4th February If you buy a CDMA phone from a third-party retailer, you'll need to call your carrier to have it activated. If you buy a GSM phone, you'll need to purchase a SIM card to put into your phone that will activate your phone's network capabilities. CDMA phones bake in compatibility restrictions that are difficult to get around, while GSM owners can simply take out their SIM and replace it with one from another carrier. Most CDMA networks do not allow the use of a phone originally purchased from another carrier even if the phone is otherwise technically compatible.

This is an important restriction to remember when going with a CDMA network. If you decide to switch networks later you'll likely need to buy a new phone even if the network you're switching to also uses CDMA.

While GSM is more open, the frequency bands supported by a phone can still restrict access. There's a number of bands from MHz to MHz and the bands used can vary from market to market. You should double-check your local carrier's band usage and make sure the phone you're buying supports the same.

With that said, GSM is concentrated around a core of four bands, those being , , and A phone that supports all four can be used in most countries, which is why GSM phones compatible with all four bands are often called a "world phone.

LTE is a new standard that's come into vogue over the last few years. The highest adoption of LTE can be found in South Korea, where it commands the majority of the market. So far it's used primarily for data, but standards have been drawn up for using LTE as a replacement to traditional cellular networks. This standard uses a SIM card, so users can switch networks by replacing the SIM if the phone is compatible with the new network. With that said, at this time phones that use LTE generally use it only for data, but not for voice.

That will change as carriers like Verizon move to LTE-only networks, but this process could take many years. While it has the potential to be a global standard, there are some obstacles in the way.

Outside of South Korea there's no market where LTE's reach is more than a quarter of the services available. South Korea in general, and Verizon Wireless in the US, are exceptions to the rule; in most markets, even carriers that offer LTE only offer it in a slim selection of the total area they cover. And then there's the problem of spectrum. The same is true of LTE. They used embedded serial numbers to identify their users to carriers.

This meant three things:. Thus, most newer phones also take SIM cards. Does that mean you can switch phones between carriers? It will be easier, but you still have to make sure your phone has different frequency bands.

We could send you a Starter Kit for free to see if it works. Just reach out to us at help usmobile. I like the LTE phone better because it has more upgrades. Thank you. All the best!

I am going maybe moving permanently to Lagos, Nigeria. I did try to see if the local Verizon phone store could accommodate this phone and they said they could not do anything for me. Reading your info, it looks like maybe they could have helped me out, maybe even with an international cell plan. The phone has a phone number of in setup and an IME xxxxxxxxxxxxxxxx.

Do you have any suggestions Thank you. I hid your IMEI and phone number for privacy reasons. You should reach out to us there.
