Looking for a clarification here before I make the jump to a dual sim phone. Located in the US.
My goal is to combine 2 services into one phone. I have a primary Verizon MVNO service that I use for Calls, MMS and Data. I want to add a second SIM, preferably also a Verizon MVNO, for Calls/Text.
I have seen some comments indicating that you can't use 2 CDMA SIMs at the same time.
If that is the case, the only option for the second SIM would be a GSM service, correct? If that is the only option, can the second SIM can only be used for Calls and Text? How about MMS? I assume NO for MMS on the second SIM.
I was considering this phone because it seems that both SIM slots support CDMA carriers. But, if you can only use one CDMA SIM, and am forced to go with GSM for the second SIM, I will reconsider the cheaper ZTE Axon 7 option.
MMS doesn't work on this phone.
When I spoke with Verizon about this, they stated it was due to the phone being "unknown" on their network, so MMS limitations are enabled as they can't identify the phone. This is because Xiaomi doesn't register devices with all carriers.
Personally, I would keep looking. SMS, calling and Data have been working fine.

For all Verizon MVNO customers (Page Plus, Straight Talk w/VZW sim, ROK Mobile w/VZW sim, etc)
are you able to get a data connection while you are talking on the phone? I ask this because we are unable to activate "Advanced Calling 1.0"
New CDMA phones do not have two radios(voice/data). The issue exists on both CDMA carriers. I moved from the Evo LTE which had the dedicated LTE radio to allow data during calls. The 5x does not have the hardware to allow data during a standard call and will only be achievable when the carriers implement VoLTE.
Hi of the blackview 9500 Pro it's not a complete idiot and I'm not afraid to get into the kernal. But like many I've gotten spoiled to the one click wave of rooting and hoping to find the same for this one. The main reason why I need to do this as the frequency bands on this phone will match 4G LTE for AT&T and already know it works for volte4g Cricket which is AT&T. But with this phone it will not under AT&T SIM card you like anything but 3-g band but the Cricket SIM card will utilize the 4G volte band I'm hoping to find some tools to modify this so I can have 4G LTE or volte on AT&T SIM card. Thank you looking forward to reply
Are you sure the native ATT Sim doesn't work? I have a Blackview 9500 (not pro) and my ATT sim shows 4G VoLTE. My second sim is Google FI and it shows 4G.
Sim
I cant be 100% as I have had the phone for less than a week. I went through every APN attached set up I could find. And to note it is a brand new sim card from the att store. I was going to try and switch sim2 (working cricket 4g Volte sim) with sim card 1 and see if sim2 is still 4g... I was hoping to avoid that due to in the past I had to call separate support lines to activate the IMIE... then depending on result possibly have to rinse and repeat back to back calling 2 different support lines... Ugh!
Could you many post what ur APN settings are many I missed something... Note*I was looking for root because I read that you can open up controls/ mods you wouldn't have otherwise with APN
Thx
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.
Hello all!
I have an LG G7 from India, model G710EAW. I moved to the US from Canada and the phone isn't entertaining T-Mobile or ATT SIM cards. When I insert them, service works for a little bit and then immediately switches to "Emergency calls only". T-Mobile's website says my phone IMEI is compatible with its service.
The strange thing is that the phone has two SIMs from Canada roaming - one on the T-Mobile network and another on ATT. No issues whatsoever. And when I check the bands in Engineering Mode, I can see one roaming SIM running on LTE Band-4 on T-Mobile. The other roaming SIM is switching between LTE Band-2 and LTE Band-5 on ATT.
T-Mobile uses bands 2,4,5 mainly, and ATT uses 2,4,5 among other bands.This leads me to believe it's some kind of a network restriction preventing my phone from latching onto these networks directly.
I've made tons of calls to T-Mobile and ATT so I'm no longer interested in pursuing them with this.
I'm wondering if cross-flashing a different firmware might help fix this issue. I remember reading on this subreddit that the Google FI firmware may work for T-Mobile bands. I'm not sure I understood that correctly.
Can someone confirm if that's possible? Does this make sense? I'm hesitant to buy a new replacement phone when my G7 works so well.
Thanks!
I'd like to buy a OnePLus 11 from amazon but does it support dual active sims? I'd like to be able to load balance my data between the 2 sims from different carriers. Is this possible?
Or combine the data throughput from 2 sims from the same provider. Is this possible?

Yes it does. You can use two physical sims or one physical and one esim. I use two physical sims. Verizon and T-Mobile.
As for how dual sims work in Android... You select which sim you want to use data one. You don't use data from both sims at the same time. Though, you can easily pick which one you want the data for.
Both will be able to send and receive calls and texts. Though you pick your primary/default sim for what calls and texts default to.
Thank you!, Now if I can just figure out rooting so I can get call recording going.
That's not dual active. That is dual standby. You won't find any phone with dual active sim in US.
Did you need to buy a dual Sim tray?
Thanks
Oneplus has 3 sim slots: dual nano sim tray and one esim.
Tried to dual esim and sim together but some reason on sim can do nothing but text can't use it for calls since I want esim for data
Well if u use esim and sim, sim can't be Verizon
