Is it possible to get only 3g on a 3g phone by switching it with a LTE sim card from sprint, and NOT activating it with them (not telling them the switch)?
I have this sprint galaxy S4 SPL-l720 That I unlocked for using T-Mobile sim. The weird thing is if I change network preference to cdma I get sprint service on T-mobile sim. If I change the network settings back to GSM I get T-Mobile service. How is this
possible with T-Mobile sim?
is the Lg G5 Verizon is unlocked and can be used for any GSM carrier in united states?
Yes.
Yeah this phone is unlocked but I am not able to get 4g or 4G LTE on the phone with H2O Wireless
LG G5 Verizon has 3 network mode
1. Global this mode gives H (HPSA) and calling on H2O wireless
2. LTE/CDMA this gives 4G LTE but on calling it says SIM Card error or no SIM Found
3. LTE/GSM/UMTS - This initially offers 4G but as i start calling it change the Data service to HPSA
Any Solution Guys?
I tried everything but seems like Verizon Lg G5 only support the HPSA for GSM network and do not support 4G LTE for CDMA networks..
I dont know how to change the bands etc on Verizon Lg G5
Specific to dual sim with Tmobile and Verizon - Unlocked version 7 pro:
When Tmobile SIM is data sim, both lines show VoLTE in status bar, and 4G under each sim. When Verizon is the data sim, only Verizon sim shows VoLTE, and Tmo is UMTS. Could this be a provisioning thing on tmo side? They see my phone registered as 7 Pro, but Tmo billing site shows unknown device.
Or does TMO require data for VoLTE and Verizon is looser allowing VoLTE when not on data because they have no 3G to fall back on?
Just wonder why Tmo falls back to 3G and doesn't use VoLTE when it is not the data sim? This implies there is something better about falling back to 3G when possible - maybe battery life or coverage?
I'd also like to know this if anyone can explain
Acknowledging that this post is rather old but I am facing the same issue. I have the issue with my 2 T-Mobile lines that I'm using in an unlocked OP7Pro. No chance to get VoLTE or VoWiFi going for a line unless it is the active data line. Given that T-Mobile wants to go LTE (and 5G) only early 2021 they should get this sorted out...
@FSOP @chromedome have you found out anything more on this topic?

I think it has to do with Verizon only has LTE on this device, so no matter what the Verizon connection is LTE.
Has anyone SIM unlocked an ATT A51 and is using it on TMobile? I want to switch from ATT to TMobile but when I go to check compatibility of the IMEI for BYOD It says that this phone does not support key features. Your phone doesn't support Extended Range LTE or Voice over LTE technology.
