Hi,
Most of mobile phones are only capable to connect to GSM networks. In my country, CDMA is almost dead. Only Smartfren Telecom was left here. It's a CDMA operator that working on bringing LTE-A across Indonesia (even if it's a GSM service, that's why I said that). It has self-branded phone 'Andromax' that works on both CDMA & GSM networks (but not all). On some countries it's even already dead. May be you could come to Indonesia and purchase one Andromax smartphone on local stores here :silly:
The only suggestion I could give to you is only to use GSM operator. It has so many advantages and enhanced technologies. CDMA is almost dead and outdated.

Ok guys Here is my problem
I live abroad and I have a Verizon Galaxy S3 with unlocked SIM capability so I'm using it as a GSM phone. The problem is that my GSM network provider does not have a 3G network, however, there is this other mobile network company that does offer a 3G network but it operates on CDMA. So I flashed my phone using DFS to the CDMA network and I managed to get the phone work for both calls and Data. But now since I usually use my GSM number I have to switch back and forth between GSM and CDMA whenever I want to use data and that is pretty inconvenient, in addition, whenever I use 3G I loose my GSM connection.
So what I was thinking is whether I can activate both my GSM network and the 3G connection from the CDMA network at the same time so that I can surf the web with 3G speed and make calls using my GSM number at the same time.
To be honest with you I've been trying to get that done with no hope, I've tried all the modes the "Phone info" app with no luck, so I'm here now asking for your help.
come on guys
I can't believe no one here does not have an answer
Hello! I have been at this for a week now.
This is my situation, I bought a fully unlocked dual sim wcdma phone (Mpie 909T) running 4.4.2 KitKat.
I want to use this phone on my straight talk plan, but I only get service from Verizon wireless where I live.
I did some searching and found that I could use a R-UIM card to pick up signal from Verizon BUT I can not find where to buy one at (unless I buy bulk for a couple hundo). So I'm at a loss. I didn't realize that I didn't get service from at&t or T-Mobile till I got the phone and went to the straight talk site and it told me to buy a sim card activation kit, (checked on AT&T site to make sure I would have service and it showed that I would)... so I went and bought the kit only to find out that they actually don't have service out here. ? so if there is no way to find a r-uim card, would there be a way to change the radio frequencies in the phone? But I would also need a MEID # to activate on straight talk CDMA (Verizon towers). Or can I get one of those sim read/writer kits on eBay and program it to work?
I have not rooted the phone yet.
PLEASE HELP!!! I love this phone!!
I've been using the phone via WiFi from my old dx2 that's currently active.
Sadly, you cannot access a CDMA2000 network like Verizon's from a device that does not have a CDMA2000 transceiver. CDMA2000 is technologically incompatible with GSM and UMTS (sometimes called WCDMA). There are some dual mode devices, but Verizon explicitly forbids non-Verizon devices on their network. Even if you could somehow get a RUIM for Verizon, and their blessing to use it, your phone would not work unless it specifically has a CDMA transceiver in it. (remember, CDMA and WCDMA are not the same)
You need a device that supports not only the right technologies, but also the right frequencies. Most Dual-SIM phones are based exclusively on GSM and UMTS/WCDMA, and often operate on frequencies that are not comparable with US GSM operators. AT&T operates on GSM850, GSM1900, UMTS850, UMTS1900, and several bands of LTE. T-mobile operates on GSM1900, UMTS1700, UMTS1900, and several bands of LTE as well. However, most networks outside the Americas use GSM900, GSM1800, UMTS2100, and LTE800, 1800, and 2600.
You can use a site called GSMArena to check which bands your device has. If you want to use a CDMA carrier (Verizon, Sprint, and many rural operators in the US), you generally have to buy a phone with their branding or one of their partners.
Sorry to be the bearer of bad news
I have similar question. Since I am currently using ST with a Verizon phone ( CDMA) could I buy a new phone to replace current one ? And does it need to be another CDMA phone? And what is LOCKED/UNLOCKED have to do with it ?

This is a very large problem. I am in the same boat. Up here, we have Verizon,and ATT. that's it. My first phone here was ATT. worked great in town. As soon as I got to my house dead.,... I bought a Nexus 6 popped the Verizon SIM in it called straight talk they registered me on Verizon's network and boom Full LTE, and VoLTE. My issue now though is I want to try other devices and it seems that the N6 is literally the only non branded phone I can use. There are some awesome new Chinese devices I would love to try and on paper have the correct signals but still claim no Verizon. I am frustrated and stumped after weeks of research and conflicting reports. Does anyone know what is going on? Thanks in advance

P version of S5 mainly belongs to Sprint networks, yes you can unlock it and use it with other networks, but these networks work differently. I bought me gold unlocked edition and it will work worldwide, but I will have some internet issues and I have to use GSM SIM Card, our sim card is for LTE connectivity and CDMA is programmed in like cricket does. Hope this explains, also try many different providers and see what does and doesn't work right. You can do the research for people who don't know what's out there, and S5's are all over India although they have hex core version.

Thought VZW and SPR are giving SIM unlock service under the certain condition.
http://www.verizon.com/about/consumer-safety/device-unlocking-policy
Like VZW clearly states on their website, that they don't usually lock their 4G devices, so I guess S7 is included?
So as SPR
https://www.sprint.com/legal/unlocking_policy.html
you just have to use your device in certain amount of time on their network and they can unlock it for you.
Unless you can't connect to their network, I really don't see the need of any "programming" or "unlock SIM" that you do refer to.(though unlock SIM doesn't exist for Galaxy S7)
And lets talk about using your device on CDMA network. You have to be aware that which CDMA is used by your career and on which band, as CDMA is mainly ONLY used by USA,JAPAN,KOREA,China(sorry if I missed any) I think very few device supports CDMA, so it might be quite DIFFICULT(or even impossible) to use GSM device on the CDMA network.
Maybe you need to clarify a bit what information you need exactly?
In yemen we use cdma on cdma2000 ev-do band and gsm so My phone is compatible with this two network(s7/sm-g930p).why i need to use programming sim becuse to use both network cdma for internet connection and gsm for calls but not in the same time.i have to swith network band to use one of them .in phone store they have a method to unlock sim and progamming sim to work on cdma.i don't now the method but maybe by dfs .
Hi all,
I've been having a hard time understanding the way CDMA companies work with mobile phones.
In Yemen, there are 4 carrier providers. 3 of which are GSM 2G companies and one which is CDMA LTE company.
The CDMA company is called Yemen Mobile.
Ever since they introduced 3G internet, all mobile devices had to be brought to IT geeks to configure devices to use 3G using DFS, CDMA workshop, or qpst and many other tools.
Now when the company introduced LTE, the same thing happened, people had to bring their devices to IT geeks working on shops to have them configure their mobile devices.
Standard configuration through mobile access points does not always work.
When I traveled to eygpt, I got a vodaphone SIM card and once I inserted the SIM, everything was configured automatically.
What is other companies worldwide have that Yemen Mobile doesn't?
This is frustrating. When I turn LTE data on, my phone becomes out of reach. I can't receive calls on as IT geeks say my phone cpu is snapdragon and I used the same phone in Eygpt with 4g working like a charm.
Can anybody explain?

This is the main issue of CDMA companies with mobile phones. In the previous week I went for a tour out of the CDMA range and due to out of the range I haven't even open my website on phone to check it progress because of the net issue. When you switch from one mode to another so it stop even opening browsers.

The CDMA technology approximately dead because the US Carriers which introduced it transfer its towers to a new LTE technology and uses VoLTE for voice calls.
In Yemen the situation is different because the company (Yemen Mobile) hasn't upgraded its equipment since CDMA/EVDO first days, and now the company want to be the first to introduce LTE services but it fails until now because the compatibility and their towers does not configured with right settings.
I have Galaxy S20 FE 5G from US cellular, I inserted a 4G sim to it, it's either works in CDMA or LTE modes.
can't work at the same time.
I tried to play with some settings in DFS but I finished with neither LTE data nor CDMA signal.
but luckily I restored EFS2 and now working either CDMA or LTE.
There is another carrier (GSM based) in Yemen called (YOU) just add the Access point to the phone and it will work immediately.
