[Q] How to Unlock CDMA Networks for Other Regions in HTC android phone - Android Q&A, Help & Troubleshooting

Well I have HTC One Max 809d which is the only version that have CDMA+GSM Dual Sim Feature . Its imported from China but I am unable to use any CDMA sim in India as it shows no network but I can use GSM sim in India on its second slot . So I think it first slot i.e CDMA may be locked to its original network or region i.e China Telecom and China Region.
I have searched a lot on this and does not found any help but found this is a general problem on all dual sim cdma+gsm mobiles imported from china.
I have already tried various steps like unlocking bootloader, s-off , changing cid but did not receive any success on unlocking cdma network.
I also want to install gapps but there is no custom recovery for this version on one max only availabe is FOR sprint t6_spr , t6_vzw,
and mine is t6_dwg.
So Please help me in this .
Thanks

Well that goes against the CDMA standard. I know india phones well and the dual sim is for dual GSM sims or a CDMA data sim. CDMA is completely different tech then GSM that uses sim cards. If it is locked then you will have to call the Carrier that released the phone and have it unlocked but I think you will find even then you will only get a data sim with CDMA

Need Help for Huawei A199

Dear all,
I just purchased a A199 Huawei dual CDMA/GSM phone from Aliexpress. Prior to purchase i had confirmed with seller that phone isn't locked and that i would be able to use my own provider SIM cards.
When I received the phone only the GSM SIM is detected, the CDMA SIM isn't detected despite using the same 800 Mhz frequency band (CDMA 2000). I then tried to download a ROM file from a chinese forum shuajizhijia.com, after the flash my phone kept rebooting itself continuously.
Anybody have any idea how to solve this?
Thanks.

Hello guys,
Mate 10 Pro C636 Asia here.
I have to travel to Africa for 6 months and I put my Malaysian SIM(Maxis) in the second SIM slot while the Nigerian SIM in first SIM slot.
Please, I want to know if this configuration will be able to detect firmware updates or do I need to put the Malaysian SIM into the first slot?
Thanks guys
Someone should please help here.
1. Do I use only Malaysian SIM?
2. Can I use Malaysian SIM and my current region's SIM? If yes, which should be in slot 1?
3. Can I get it with any other SIM?

for this you need to check on what frequencis their lte and 3g are working. IF they are the same, everything will work. Sim slot doenst matter i think
Doesn't matter if u use any sim slot.
You get updates even without sim card over wifi.
The moment you get updates depending on imei numbers.
