[Q] How does cid or callers number show up when using non verizon SIM

Hey all,
Are any of you using your verizon Note 4 with another non-verizon Sim card? If so does the callers number show up correctly?
Just checking, as I currently use a verizon Note 3 and sometimes use it with a net10/att sim card. When I do this, all calls show up with a +1 country code as if I was using the phone internationally. I am considering getting the note 4 developer edition, but do not plan on keeping my verizon account much longer, so want the calls to show up properly without the +.
Thanks,
Chris

Must be nobody uses the Verizon variant with other US carriers??
It seems to me that at least Bandwise, that the Verizon versions of the Galaxy phones, especially the Developer editions when available are the best deal. As it works with pretty much all the gsm carriers as well as Verizon. I have used the S4, and the Note3 with Verizon, and ATT as well as several other GSM carriers. Only issue that I have when using them on gsm carriers is that the phone responds to incoming calls and messages as if the incoming number is an international call. Even if I am in the US, and the call is a US call the number comes in as +1-111-111-1111, instead of 1-111-111-1111.
I have been planning on dropping Verizon when my contracts all run out. I like the idea of being able to switch carriers at will. If I buy the Verizon variant then that leaves me with the ability to switch to any gsm carrier and Verizon, whereas if I buy the unlocked version I only can use it with the GSM carriers.
Best,
Chris

eSim T-Mobile

Hello everyone, Just would like to know if anyone tried to activate their Pixel 3 XL eSim on T-Mobile? If it's possible, do I need to have a physical sim from a different carrier? Will eSim work overseas when roaming? Thanks

I was able to activate my esim on tmobile when people were going through the 'back door' method of not ever mentioning that they want to activate the esim. There has been threads on Reddit that they are no longer allowing that and that customer service is catching on and no longer allowing activations of esim on tmobile.
You do not need another physical sim from another carrier as your phone will work fine with just tmobile esim. Having that physical sim available will allow you to pretty much go with any other secondary carrier that you want to (just can't use both at once)
As far as the overseas when roaming, that I have to defer to as I don't (or haven't) traveled overseas yet. I would 'imagine' that it would work just as if you had a physical sim in your phone as many European carriers already use esim and is not a new technology over in the European countries.

Did you notice any difference in the signal reception? Is it the same as the physical sim, better or no different? Thanks

I haven't noticed any difference in signal.

After 5 or 6 times trying using different methods (Twitter, FB, app/site chat, etc.), I finally convinced a rep to activate my eSIM a couple of days ago. It does take some massaging to get them to agree to it. Most of the time I was told there wasn’t a way to activate on postpaid. In the end, I experienced faster loading times on sites and faster downloads my video and podcast apps.

Dual SIM Technology and how it works on the 7T

I'm having trouble finding out what type of dual SIM technology the 7T uses. Is it DSFA of DSDS? Will either one allow me to take a call from two different carriers at any time? FYI I'll be using Verizon and AT&T.

OP has always 'only' DSDS. So you can only make one call with one card at the same time.
The other card is disabled during this call.

Thank you for the info. If I am currently not on a phone call, the phone being idle, are both Sims able to receive a call at anytime?

yes, of course.

Dual SIM technology? I'm on the T-Mobile variant. I'm confused.

DSDS = Dual sim, dual standby, where you have two sims from two different carriers. When one SIM is active on a call the second goes idle. DSFA = Dual sim full standby, even if one sim is active on a call the other continues to function, although I am not certain of the mechanics of how a user handles two calls at once.
These are very popular with frequent international travelers, or when someone has a company phone and a personal phone but doesn't want to carry two devices. They really haven't caught on in the US because carriers for the most part have similar coverage and don't sell them. The carriers don't want their customers to be customers of other carriers too.
Imagine living in Belgium but frequently traveling to the UK and needing to use a mobile phone in both places. The roaming fees and long distance charges would be outrageous. With a dual sim phone a user could have a Belgium sim card and a UK sim card and be able to use the appropriate sim as needed without having to place the wear and tear on the phone doing sim swaps.
I have tried to find a dual sim phone which functions well in the US. I have a dual sim S9 from the UAE market, but for some reason the data is very slow compared to a single sim S9 for the US market. I also tried a Sonim XP8 which worked well enough until the phone figured out it was in the US and disabled the second sim slot. Apparently Sonim does not want the XP8 to function as a dual sim phone in the US.
T-Mobile has disabled the second sim card slot in the 7t, for whatever reason. I have a 7t coming from direct from the manufacturer and I am excited to see how well it works as a dual sim phone. I have a line on TMO and a line on AT&T, and I don't want to carry two devices if I don't have to.

I had no idea. So if I but a dual SIM card tray and flash the international version software on my T-Mobile variant I should be able to have dual SIM functionality?

This has been done on other model phones and should be the same with this one. It was the same price point for me so I just cut TMO out of the deal. Just be careful flashing other firmware, if you are a TMO customer you wouldn't want to loose Band 71.

SM-N976V Note 10 plus 5G portability (carrier switch)

I'm looking to spend on Note 10 plus 5G, currently on Verizon but the biggest question that I couldn't find the answer is if in the future, I will have to stay with Verizon forever if I want to use 5G on this phone.
Samsung released different snapdragon models for each carrier, but what if I want to switch to Tmobile or AT&T with this phone? Is there a workaround to make these phones work with different carriers, especially with 5G?
S10 5G is out for many months, but I couldn't find a thread showing portability. Although selling the phone for a discounted price and buying other one that works on different carrier is an option, looking to find if it is practical to use 5G when we switch carrier.
Thank you

once its sim unlicked it will workbwith other carriers.. ive tried it on multiole sims from dif carriers

The lte radios should be the same, the 5g will never work across carriers for now considering theyre taping into different spectrum. Modems and antenna designs are different between the different 5g methodology each carrier adopted.

That is very nice to hear. Does the phone work with other carriers once sim unlocked without changing the phone software? Does 5G work on other carriers too, if the bandwidths match? Thanks

I may not understand much details of these modems, however my understanding is that there are some 5G bands common between carriers.
Verizon holds 76% of total available 28GHz spectrum bands and and 48% 39GHz 5g spectrum bands.
At&T holds 40% of 39GHz bands and Tmobile holds 12% of 28GHz bands. If I'm not mistaken the modem in Note 10 5G model supports 600MHz which is new Tmobile band. So, if Note 10 modem supports those 2 5G bands on verizon, technically it should work on at&t and t-mobile too? Although these may work in different cities as of now

Yes and no, I don't know if it has the right antennas, they matter to match the signal length and the obvious is how locked the radio is.
You forget Verizon are evil about keeping their phones there.
It could be the phone is capable but will never be able because it's a Verizon phone and they nerfed something.

In the past we were able to unlock blocked antenna bands using Qualcomm QPST tool and hope there will be possibilities in the future. It's not that Verizon is evil, it applies to all carriers. There has been court ruled regulations that enabled users to take their device to other networks, but blocking 5G would be inconvenience to users, as we all know 5G is the future. I'm going to grab a Note 10 plus 5G for now

technically they wouldnt be blocking anything if they just dont include the antennae/functionailt.. its then up to the user to research and purchase if it suits their needs.

Follow up:
After Verizon unlocked the phone, surprisingly 5G works with Tmobile without any modification. Of course not all the bands. Haven't had 5G signal so far and suddenly when I'm standing near a 5G antenna in downtown Manhattan, I had full signal

I have the same phone. I was not able to see 5G with TMobile or AT&T. I am also not able to get the Verizon hardware off my phone. ( boot logo, etc.) Any work arounds?

Odd. I have the 5G on VZW thats unlocked. My phone works fine with my TM SIM but does not pickup 5G even though my OnePlus 7T Pro McLaren gets 5G.

nope.
the n976v only has vzw and gcf csc codes on it which both use the vzw sales code n network code.. changing carriers should work but on network as the csc should recognize this and load the correct apns n such but the bootani n vzw stuff is there to stay..

not odd.. its a vzw branded 5g device.. its hit or miss on other 5g networks.. they typically use different bands and frequencies and 5g variants dont contain full csc for other carriers like the non 5g devices

So I'm having an issue, I'm trying to get my phone to work with Total Wireless but for some reason I cannot adjust the APN and they can't send me an update to my sim card. I can get the calls and text to work and it shows 4g but no data due to the incorrect APN. Its all grayed out with no way to add or configure it. The IMEI also says its not compatible with Total Wireless which is weird since all other verizon phones have worked before except this Note 10+ 5g.

Where did you buy this phone? I had the same issue, when I changed the code to GCF from VZW. I had to send the phone back to Samsung, as the local samsung experience store couldn't even understand the problem. GCF is for Samsung diagnostic purposes only and they had to change the motherboard board on the phone in order to fix the issue. If your carrier 5g mmwave band is one of the band used by Verizon, you'll be able to use 5G with this phone. I was able to use 5G in NYC with TMOBILE, but not when I moved to a different state.

I can relate the issue you're facing. I was using this phone with TMobile 5G in NYC, but when I moved to different state, I can't get the 5G reception. In order to understand this further, you need to understand the frequencies supported by TMobile and frequencies owned by Verizon. TMobile shares one of Verizon's mmwave band (only around 25%) and these antennas are limited to only few metro cities. Even if you live in one of those big cities, you need to stand close to the 5G antenna in order to get the 5G signal. I remember that I had to stand within 50ft from the antenna in order to get 5G signal (downtown Manhattan near Meridian Lane and Water st).

So I'm new to this. Ive got a Note10+ 5G from Verizon (SM-N976V). Ported over from Verizon to At&t. Works fine accept its on 4G LTE (no 5G... the Samsung S9+ went over to 5G no issues). I am told if I flash the phone to the unlocked firmware it should get rid of the Verizon "lock" and work. I have tried this as per help form Android Central however having no success flashing... I am not exactly that savvy with this stuff... Please help

You can network unlock it pretty easily even if the phone isn't paid off yet. Download setedit by 4a from the play store:
https://play.google.com/store/apps/details?id=xyz.paphonb.systemuituner
and change the setting "vzw_network_lock" from a 1 to a 0. You'll have to buy the expansion pack from 4a to have a foreground guardian that'll prevent it from going back to a 1.

S20 (0 - Hong Kong variant or F/DS - Dual SIM international) in Canada

Hi,
Does anyone have the 0 or F/DS variant in Canada and do any of the following features work for you? If they do or don't please also post your carrier (I'm on Telus).
- WiFi Calling
- LTE-A
- VoLTE
- e-SIM
Looking at getting the Hong Kong variant since e-SIM isn't even a working function in Canada or the USA for that matter when the iPhone and other phones get it. Every year I push myself closer and closer to just getting an iPhone. Boot loader completely locked down, check. Can't root, check. VoLTE doesn't work unless it's a carrier phone, check. No e-SIM, check. Like what's the point of an Android anymore? All the above features work on an iPhone no matter what carrier (or country for that matter) you bought it from. Samsung is a mush of CSC files, hardware variants, LTE bands...
Thanks,

No such thing as a perfect device, likely never will be. Best option is to list feature priorities then decide. i have the Hong Kong variant on T-mobile USA. Dual SIM which eliminates the need for an eSIM, bootloader is unlocked, can root the device. WiFi Calling and VoLTE function but no Carrier Aggeration (LTE-A). I wouldn't consider the F/DS variant, it has the Exynos SoC. Not an iPhone fan either, not impressed with their devices or ecosystem.

Thanks for the reply, its nice to see at least VoLTE and WiFi calling work (at least on T-Mobile in the USA). Anyone here on Telus? LTE-A isn't a priority considering a single band is typically fast enough for me these days, if I'm on a lower band it's for a reason (like distance). Does your dual SIM phone still support e-SIM? It's nice just to scan a plan and get going verses hunting the airport / local stores for a SIM.
Priority for me goes:
1) WiFi Calling
2) VoLTE
3) e-SIM
4) LTE-A

eSIM isn't available unless you aquire an International Variant with the Exynos SoC. I'm not aware of any Dual SIM devices which support eSIM. IMHO you have to really want the eSIM to sacrifice a device with a vastly inferior Exynos SoC.

No no, dual SIM would be best in that case. Anyone in Canada can comment on the above?

Does Wifi-Calling work on both SIMs or SIM/eSIM on the S2, if they are from a different region?
Both my providers allow Wifi-Calling abroad.
Can anybody please confirm?

I have a Telus S20+ only support VoLTE, no WIFI-Calling. The reason I get this phone because of esim such a big disappointment.

I have Hongkong variant s20 5G (sm-g9810) using in Sri Lanka.
The phone supports physical dual SIM , dual 5G, VoLTE , VolWIFI.
Only disappointment with Hongkong variant is the lack of e-sim support and Call recording feature.
