My C3 rmx2020 10 a57 only shows 1 Sim in settings. Should have dual volte options but it doesn't only show 1 Sim there are no settings for Sim 2. I'm in Australia . Both Sims support volte. When I put them into Sim 1 space they both show volte active. Phone was originally locked to Optus prepaid who don't support volte. I unlocked network restrictions successfuly & did a system settings reset put in my volte supported Sims but no change. I have volte on both but only Sim 1 options. In notification drawer settings there used to be a button for switching default data Sim. It's no longer available. Any ideas?

Hi.
I have two 4G sims in my phone, I wish to use Data from one sim and Dial via VoLTE from other sim, but I can't.
The sim that is set for Internet only works the other Sim is blank.
Or is it that only if other sim has 3G data it can work?
Can anyone help.
Xiaomi mi5 is 4g+3g standby. You can use Volte from the 4g sim and data from the 3g sim.
mi 5 supports only one sim slot to be used as LTE at a time. Jio does not have any network other than LTE so your second jio sim will not work because of absence of 2g/3g network in Jio.
Hi I have a Nokia 8 (TA-1004) which is dual sim.
I have a 3 sim and a plus net sim installed.
When I select the default sim for data it works, same for messaging.
BUT when I open the selection for calls i cannot change it from "ask every call" to either of the sims though it looks like it should be possible.
Anyone come across this before? what is the answer? phone is latest OTA updates.
Nokia 8 not permitting selection of preferred sim for calls
Hello I have exactly the same problem as described below by Pontprennau. Also on a Nokia 8 (TA-1004) in the Network & Internet screen under "SIM cards" and then "Calls". Setting preferred sim for sms and data are permissable for both Sim 1 and Sim 2, but setting the preferred sim for calls is not permissable and continuously force-defaults back to the "Ask every Time".
Can't imagine that the network provider has anything do with this problem though ie whether it is a T-Mobile, 3 or any other network.
If any information/resolution on this are available would be much appreciated. I have the latest OTA updates provided by Nokia/HMD Global.
Thanks

In Settings / Wireless & Networks / Dual SIM, see that only one SIM (you can choose which) can be 3G/4G
Hence one SIM will be on 3G or 4G, second SIM must be on 2G - but if your operator for that second SIM does not provide 2G you will not be able to use that SIM
In Settings / Wireless & Networks you can disable 4G and in Preferred Network type you can force GSM (2G) only - that way you can test which of the two SIM cards / operators provide/have 2G signal

In Dual SIM Settings you choose one which is 4G, the other will be 2G/3G
Cannot help you more, I have both SIMs 2G/3G/4G, hence no matter how I set, both work
Try playing yourself, test both SIMs one by one only, in one and the other slot, with various settings (4G enabled/disabled, Pref net 4G, 3G, 2G only)
Maybe you have problem with one of the SIM cards or one slot
I saw something a bit odd here. It says here on specs that secondary sim only supports voice but from what I know is that both SIM cards support data. Is there something wrong here? Do both sim slots not support data? To the best of my knowledge with this phone you can have two SIM cards and use data on both of them allowing you to download two WeChat apps and have two numbers for each WeChat account on one smartphone. Is this not the case now?? See link from HK below and look at the bottom of the specs page for supported bands on SIM card tray.

Hi
I don't have a second SIM handy but looking at the settings you set the phone with a default SIM for calling and a default for data. Makes sense you would have to do this. So outbound calls and default use of data is pushed through either SIM. Don't know if that helps....
Found a SIM and popped this in. I now have another option enabled which says switch data connection between calls. So the option moves the data to SIM 2 when taking a 4g call on SIM 1....

Single SIM only in Canada VOG-L04 model.
Hi all,
I've just purchased a Verizon G998U with cracked front screen and back and found that the phone is google locked - FRP Locked. According to the seller, it was Verizon unlocked prior to the sale. Tested the phone with my local Malaysian SIM Card and I was getting signal from it prior to getting the screen replaced and FRP unlocked.
I have managed to get the FRP Lock removed and a factory reset later allows me to setup the phone properly with my own Google Account but when i'm putting in my Malaysian Sim Card, it says that this is not a Verizon sim card.
Any ideas on why this is happening? Will an sim unlocked phone be reverted back to a locked phone after FRP lock is removed?
Thanks in advance
Ask the seller for the unlock code used before
Noted miravision, what do i do with the unlock code then? Putting in my Malaysian sim card and rebooting the phone does not ask for any unlock code.
Depending on whether the seller used an official unlock authorized by Verizon or used unofficial means, your seller should help you further in good faith
Noted with thanks, miravision. I will check with the seller and will update once i get a feedback from them
Update on the testing done to the phone. Didn't managed to get anything from the seller. But did some interesting testing with the phone. I've got 2 sim cards with two different provider in Malaysia - Celcom and Yes.
Flashed the phone with the U1 XAA software and managed to setup the phone with Yes sim card with VoLTE running and Internet working. As for Celcom SIM card, no signal at all and tried playing around with Samsung Band Selection App, managed to get the sim to connect intermittently with VoLTE and Internet working. Removal of sim and reboot of the phone will sometime changes the Celcom SIM to no signal at all and manual searching of the Celcom network also doesn't show the selectable network and only shows Yes 4G network.
So from the testing above, can i presume that the phone is sim unlocked? If it's unlocked, why can't the other sim from Celcom can't be detected consistently?
Anyway, the telco info is as below
YES - LTE Band 20 (800 Mhz), Band 38 (2600 Mhz), Band 40 (2300 Mhz),
VoLTE Support
Celcom - LTE Band 1 (2100 Mhz), Band 3 (1800 Mhz) , Band 7 (2700 Mhz) - VoLTE Support.
Hopefully can get some insights on what is actually going on.
Thanks in advance
