I have a question about how GSM and CDMA radios work. I have an HTC Merge from USCC (I live in Vermont, USA). They use CDMA and leave the SIM unlocked for prepaid SIM cards. I travel to Alberta, Canada on a regular basis and have access to a post-paid account on Bell Mobility (GSM). I would like to figure out if it is possible to set up my phone to work on both lines at the same time, without having to switch back and forth to check for incoming calls and texts.
Is such a setup possible?
If it is, does anyone know how I would go about getting it set up (perhaps a different thread for the answer to this part)?
On a CDMA phone, where is the carrier information stored (phone number, PRL, etc.)?
The phone is currently rooted, S-OFF, SuperCID, SIM Unlocked, running 2fastrom's USCC Gingerbread ROM.
Radio version is 1.08.00.0804
I am posting this here because I consider it to be first of all a question of whether it is possible to use both systems at the same time, regardless of the phone itself. I have added the phone info in case those who may know the answer need it. If it needs to be moved, I have no problem with that.
Thanks for your time and consideration.
All the best,
Reuben

most phones do not support both cdma and gsm

I know the iPhone 4s can use both but it has two separate antennas to accomplish this. I think it comes down to hardware.
Isn't Verizon coming up with some type of solution with VMWare for this? Where you could have two numbers active at the same time, one of them being a business number that was running in VMWare?
Yes, it is partly a matter of hardware - the Merge is set up for both systems. Still not sure if it can "listen" for two different numbers at once. Also curious about whether the phone needs to be listening to both bands at the same time if one number is CDMA based and the other is SIM/GSM based.
Verizon's solution sounds interesting - not sure it is enough to make me switch, particularly if both numbers have to be on their network.
Yes but only if you are not Verizon.

Currently Telefonica will support 2 simultaneous numbers due to a dual-sim. I really can't wait until entire networks start switching to an all IP based system. This would allow a much more flexible system then the NAM currently used.

Dual sim
It will eventually coming , we may see this type of services in near future once iphone will start shipping with GSM and CDMA unlocked version.
No its not doable at the same time
Just bought verizon galaxy S 5. Changed SIM to AT&T from straight talk. First of all was that a mistake? When ever i leave a wi-fi area the phone goes to emergency calls only. Email and text stops as well. Can't get voice mail to work anywhere
Would appreciate any help.
Thank you
Just a thought, go to settings /more networks and make sure you have the correct network checked
New to verizon galaxy s 5
The network was correct . Wondering if im in a bad area. My Iphone 4 works fine. Might be AT&T

Wait... you put an AT&T sim in your phone? This is a Verizon forum. If I misunderstood, please tell me.
Just to be clear because you didn't state it in your post, you must unlock your phone prior to using a non-Verizon SIM. You can sometimes get these unlock codes from Verizon but you can also buy them online. I've used GSMLiberty.net with success before. After that, you should be able to pop in your SIM from the new carrier and begin using it right away. In some cases, you may need to manually add the correct APN for your carrier. Find these settings under Settings > More networks > Mobile networks > Access point names. Click the little plus icon in the top right and manually enter AT&T's APN information. You may need to Google that as I don't know AT&T's APN info.
I use my Verizon S5 on T-Mobile's networks with absolutely no issues, I assume it would be a similar experience for AT&T as well. For me, I put my T-Mobile SIM card in and could make calls and receive texts, but mobile data and MMS was not working properly until I manually added the correct APN information. After that, MMS, 4G LTE data and everything is working flawlessly.
You do not need an unlock code for a LTE Verizon phone. These phones are already unlocked. One must set the correct APN.
Do not buy an unlock code!
I have used my Verizon S5 with att and t-mobile.
Good luck.

Thank you for your posts. Most of the phone works. When I leave a wi-fi area my phone goes to emergency calls only. When I go back to a wi-fi area the normal call service works again. I'm new to verizon and samsung. Wanted to use straight talk because i didn't feel like paying a fortune for service. I'll get it figured out some way.
Thank you again
Hey guys, I just saw a YouTube video that was posted yesterday where the guy shows that after the update he no longer could connect with his Verizon SIM card in the axon 7. Has anybody else run into this? Mine won't be here until Monday but if this is true I'm going to be sorely disappointed. Thanks for your input.
I am on verizon with no additional problems after the update. I am still always roaming, and my signal is the same (more bars but still the same reception). LTE, MMS, SMS, Cdma all work the same.
I'm really glad to hear that. I'm not so sure the guy knew what he was doing either... Lol :silly:

Quick question for you bud. I currently have the Moto Z-Force, but I want an unlocked phone that I can root and mess around with and unfortunately this phone doesn't have that capability. Would you say this is a great alternative in terms of functionality and specs? Tia

My VZW situation. Just an FYI post AND how to fix it.
I'm on Verizon, have had my Axon 7 for over a month now. No issues other than not having VoLTE, and the occasional software farts (Using Nova Launcher now). When I initially set-up my phone, I imported all previous apps directly from the Play Store. I should have known not to install the VZW apps that were previously installed on my HTC One M8 (purchased directly from VZW), but in my excitement for the new phone, it skipped my mind. Anyhow, no issues through 9/19. "Verizon" displayed as my carrier, and full access to the LTE network.
Fast forward to 9/20 (post B27 update) when one of the VZW updated automatically (I don't recall which of the 2 apps I had installed), and BAMM, "123456" displayed as my carrier and no more access to the LTE network (3G only). Later that evening, my VZW account showed my number with an "unauthorized, non-VZW device", whereas, before the VZW app update it showed my HTC one M8. I removed the SIM and shut down the phone, re-installed the SIM and re-booted....nada. Tried what seemed to be every permutation of replacing the SIM card, played around with APN settings...no dice.
My feeling is they booted me off 4G LTE once the app recognized I was using an unauthorized, non-VZW device. The steps below solved the issue (Provided by "vzwcdma" via the ZTE Community Forum).
"As for losing LTE connectivity, I've had a similar problem before, both on the A7 and other devices. On other devices, like Motorola devices, I could just boot into the bootloader and clear the modem state partitions via fastboot, but ZTE seems to have disabled that function in the A7's bootloader. So, for the A7, I had to mess around a bit with the modem mode. Download "Network" or "4G LTE Switch" from the Play Store. Open it and scroll down to "Set preferred network type", where it should say "LTE/GSM/CDMA auto (PRL)". There isn't really a set guide for what you have to do, but try switching into LTE-only mode, try hitting "Turn off radio" and "Turn on radio" (not Airplane Mode), maybe try "LTE/CDMA audo (PRL)", maybe turn off radio, switch to LTE-only mode, turn on radio, etc. At some point (I'm not sure what) the phone will reset its modem state, and should re-connect to Verizon LTE (and when it does, switch the network type back to LTE/GSM/CDMA auto PRL.
My Verizon account also shows "unauthorized, non-VZW device". Shouldn't affect anything. I've been using an unauthorized/non-VZW device prior to the A7 with no issues as well."

Good to know! I've had so many phones and this hardware looks so awesome for the price, but of course vzw isn't gonna play nice with it without some work. Looking forward to getting mine
Verizon still working fine for me.
After the b27 update I saw improved signal strength. I'm on page plus mvno. After driving in a fringe reception area, I lost lte,and I showed as roaming. It seemed to be using boost Mobile from what the phones network menus displayed. Axon doesn't have a mobile network setting for 'system b', only auto & home only. Tried both, rebooting each time, no fix. I ended up resetting phone, fixed it all. I then switched mobile network to home only, and hoping that it's done.
PS-after b27 I had to re-enable a couple settings, pinch for screen shot, etc.
Edit: it's now been several weeks with it set to home network only. I daily drive in fringe reception areas and have better signal strength than ever, with any phone/carrier combo. All is great, no more issues. Great phone!
For reference, I'm on page plus mvno, dropped in my activated sim from my old phone into the right-side sim slot for CDMA services. Then set to home only. Done.

Just wanted to see if anyone else had inputs of post update Verizon service, good and bad... hasn't been a ton of chatter in the last week. I have a phone on its way from the egg, trying to decide if it's worth starting a new sim card with Verizon and dealing with that work around... is getting the number off a display and ordering online still the easiest way to get activated?
Works great on VZW still. Love the phone.

I'd say that the Axon works just as well on Verizon as it did prior to the update, but with potentially better signal strength though I didn't really have a big issue with that prior to the update so I'm not sure (the T-Mobile SIM does seem to do a lot better post-update...but Verizon has always worked well).
I really doubt you'll have any substantive trouble with VZW on this device, especially if you're willing and able to mess a bit with some of the more advanced settings just in case a problem does arise. Here are the oddities, and I'm trying to list *all* of them!
1. No VoLTE or (I presume) HD calling
2. Voicemail appears to have to be accessed by dialing *86 as opposed to long-pressing the '1' key
3. Roaming icon is present intermittently
4. Data roaming *must* be enabled to ensure consistent and reliable data service
5. Verizon's website won't recognize the device at all in the Account Overview pages (mine still shows the last "approved" device I had with my VZW SIM - an iPhone 6S)
6. MMS *may* require a hack to get the proper APN, though I've had no trouble with this (I'm prepaid though); the hack requires a GSM SIM, so beware of this
7. 1X reception *seems* a tad weak in terms of dBm but functionally it almost seems better than my other Verizon phones (weird!)
8. Carrier label will be either '123456,' '002127' (EvDO only), or (I think?) '31000' when not using LTE (i.e., 1X or 3G). When on LTE the phone should show "Verizon Wireless" as normal
9. A SIM/modem reset may be necessary once in a great while it seems...so it's good to understand how to navigate to the "Phone Information" screen to toggle radio settings...also, I've found just SIM-cycling with a GSM SIM will often fix any connectivity problems as well...and sometimes just rebooting the phone with no SIM at all can help too (or a combo of all the above!)
If you can tolerate the above issues then the phone is great. I really enjoy it. I've found the Verizon side of things to be pretty reliable on the Axon 7, even with my endless tinkering with radio modes and other stuff, which has seemed to get me into (recoverable) trouble a few times.
Most importantly - the endless chatter on various forums that Verizon "blocks" the Axon 7 and other non-approved devices is total bunk. In every case where I've run into an issue it can be resolved on my side - Verizon is doing nothing whatsoever to inhibit the use of the Axon 7 on its network as far as I can tell (notwithstanding activation hurdles, admittedly)...many of the people making such claims seem to be speaking from a standpoint of total ignorance and it's kind of getting annoying, to be honest...it seems like the minute someone has an issue with the Axon 7, some ignoramus gets on the relevant forums/comments and claims that Verizon is "blocking" the device. Total BS IMO.
Good luck! As far as activation is concerned...I'd say it might be best to just go to Wal-Mart and buy a cheap prepaid phone or something (looks like the HTC Desire 526 has a nano-SIM and is only $37.49 on their website)...or maybe a cheap nano-SIM'd Verizon phone off of Swappa or eBay? That's probably what I'd do...But I know neither of those solutions are particularly helpful...VZW definitely makes it a bit of a pain.

http://www.prepaidphonenews.com/2016/02/new-policy-may-require-verizon-prepaid.html
"It turns out that Verizon made a policy change effective 1/17/16 that requires Verizon Prepaid Phones to be activated on Verizon Prepaid and have at least $30 in airtime applied to them before they cam be used on Verizon postpaid. A Reddit user posted a copy of an internal Verizon document detailing the new rule:
Effective 1/17/2016, customers who purchase a Prepaid 4G device must activate on a $30, $45, or $60 Prepaid plan and make at least 1 monthly service payment before they are eligible to move the device to a new or active Postpay account .
Device remains locked until first month’s payment is made on their Prepaid plan.
Device is unlocked automatically upon successful first month’s payment and can be used on Postpaid plan (new SIM or SIM swap).
Attempting to use an active Postpay SIM Card with a new 4G LTE Prepaid PIB smartphone prior to making the required monthly payment, hotlines the Postpay MDN (SFO 83643) . The hotline remains until first month’s payment is made.
Customers who activate on the $45 or $60 Prepaid plans and enroll in Auto Pay, receive bonus 1GB data per month.
If account is hotlined:
Data access, outgoing calls, and text messaging do not work.

So frustrating. Before update used today Verizon in upper left corner. Switched to 123456 after update. Rebooted and it went back. After another reboot it only says 123456 and nothing I do will change it back. And now when I get an MMS hangouts tells me it needs to download it but nothing happens. I never get LTE anymore either.
Edit: not sure what I did but it's back now. Might have something to do with bearer in apn settings being lte.

That's #9 in the above list that was posted. Need to cycle the modem state of the device.
so, can someone help me with a little clarification? did ZTE ever actually disable anything regarding Verizon on this phone? i know when people quote the webinar, it sounded like they were going to. i understand that the functionality is basically all still working, but i'm wondering if maybe i'm confused on the terminology.
in this post on reddit, i heard the same thing that has been repeated by some, and i am wondering if i have my band terminology confused. is the cdma part different from the 4g lte part(and that's why it's still working)?, or is sarah just incorrect?
SarahSchmera 3 points 9 hours ago
Axon 7
Doesn't work on Verizon yet. It supposedly has CDMA radios but the radio firmware has them disabled. ZTE can't by law enable the CDMA radios because they didn't get FCC approval for the CDMA radios. They would have to pay for the testing and then resubmit the device to the FCC to get approval before they turned on the CDMA radios through a software update.
And the device doesn't have the firmware for VoLTE, HD calling or WiFi calling on Verizon.

I just switched our phones from post paid to prepaid with ATT.. it seem, i'm pretty sure at least, that conditional forwarding for things like google voice do not work on ATT Prepaid (this all worked fine on att post paid and the same equipment a day ago).
If you go to the phone settings.. more settings.. call forwarding you get a network or sim card error and all the entries are blank and do not save (where you can enter a different phone number for things like what to do if busy or on another call).
Is there a known workaround by chance?
Any thoughts?
Thanks in advance
Prepaid plans generally don't allow conditional call forwarding, at&t certainly never has on their prepaid plans, and probably never will.
The only prepaid plans I know of that do allow it are from Cricket & MintSIM. There may be a few others but those two I've actually used and I can confirm they allow conditional call forwarding.
I've got a MintSIM card in my S8 now using Google Voice, conditional call forwarding works fine.

In a different forum someone wrote that they are able to use conditional forwarding, but i think on an unlocked phone.. mine was unlocked..
At least it was originally "unlocked".. not an ATT unlocked, but unlocked in general.. recently i firmware flashed it with the ATT bloatware to enable certain things to work like HD voice and wifi calling..
So at this point its ATT firmware flashed.. so i guess this is why its not working then from other reports. I'm not sure that i can undo the firmware.. i mean i think its possible but dont know the method.
I dont have access to an unlocked phone to try the sim swap trick i read about either.

I can pretty much guarantee you that it wasn't an at&t prepaid sim if they had conditional call forwarding working.
It has nothing to do with the phone or firmware, it's that at&t blocks conditional call forwarding on their prepaid plans. There isn't really any hack or workaround to make it work.

I've got a MintSIM card in my S8 now using Google Voice, conditional call forwarding works fine.

Yeah i'm not sure why they are succeeding..
Probably unrelated but my sim is still the post paid att sim card.

I can pretty much guarantee you that it wasn't an at&t prepaid sim if they had conditional call forwarding working.
It has nothing to do with the phone or firmware, it's that at&t blocks conditional call forwarding on their prepaid plans. There isn't really any hack or workaround to make it work.

The one user with success is using a TracFone AT&T SIM card they couldn't forward with the MMI code until swapping it from a AT&T Prepaid to a GSM unlocked phone - then back into the AT&T Prepaid phone and forwarding held

Tracfone is an MVNO, so that user is using a Tracfone SIM card on a Tracfone plan. Tracfone allows conditional call forwarding, that's why it works for them.
This has been a point of frustration for AT&T Prepaid users for as long as I can remember them having Prepaid cell service.
And now, AT&T allows MVNO's like Tracfone and h2O, that operate on the AT&T network to offer conditional call forwarding, but AT&T themselves still won't allow it on their own prepaid plans.

Makes sense but someone with an ATT branded Note 8 also had success.. unless their sim card is something different

I don't think you're getting the point. The device itself is irrelevant. The SIM card is the crucial element here.
With an AT&T SIM card on an AT&T Prepaid plan it is not possible to have conditional call forwarding. Anyone that tells you they had success is not on an AT&T Prepaid plan.

Ah ok i see your point.. so in theory if i had one of those alternative MVNO sim cards, it might work in the S8 then enable the feature?

Yes it would work on one of those MVNOs I mentioned earlier. I'm doing that now.

So i would have to drop the att prepaid alltogether and find one of these that "works on att" per say, not just use one of their sim cards as that wont work if using att prepaid services right?
I dont know too much about those other offerings, guessing there could be other drawbacks to switching.
My main goal was to be able to do google voice for voicemail transcribing.. if att prepaid voicemail had this built in then I would have been set.

Right. I haven't used AT&T for a while, but I'm pretty sure they had visual voicemail with text transcription. Is that not available on their prepaid plans?

I didnt see it.. not as an addon anyway.
Looks like they do offer Visual Voicemail on their prepaid plans. Maybe that will work for you.

Yea but unfortunately not voice to text or email transcription. Just a way to avoid dialing the number to listen
I had originally posted a question over at the ATT help site here.
Seems this ATT rep claims that conditional forwarding is not disabled for att prepaid.. (very skeptical that they know what they are talking about).. however i did see in the one other thread someone mentioned they have it working with an "Att Go phone" on att Prepaid.. maybe the go phones are different in some way.
At any rate the rep wants to do a chat at some point to figure out why its not working, but we will see if this gets resolved.. given what I now know, I highly doubt it.

Well they are working off a script so they just find the closest thing to the question in the script and run on the assumption that it's the right answer. lol
