Hi,

It won't register any sim card. The second (2G) slot still works fine.
Any idea how to fix the sim tray?

I have an older dual sim adapter I had used on some previous phones. I installed it primarily out of curiousity on the #2 sim slot and populated it with two freedompop (AT&T LTE, data only) sims. Sim toolkit (the app used to switch sims) shows a notification ("AT&T sim-1), but doesn't allow me to change it. It may also be reading sim #1 in the phone since it is populated with a tracfone AT&T sim, as oposed to one of the freedompop sims in the adapter on the phones #2 sim slot.
It is picking up one of the freedompop sims with LTE and seems to be working fine, I just can't access sim toolkit to change freedompop sims.
Anyway I was wondering if anybody with experience with dual sim adapters might have some insight on the adapter use with a dual sim phone. Thanks.
Hi Guys,
I have a Note 8 and I had it sim unlocked thru an online service. I was a bit dissapointed when I found out that I was only able to use my sim 1 as call and text only like the sim 2 slot after the unlock and I could not use it for data 4G. The tech guy from the sim unlocking service told me its with the software of my phone from the original carrier that has not allowed me to use data on 2 sim slots except its original carrier. Can anyone please help me how to fix and enable 4G to work on either yhe 2 sim slots?
Thanks very much!
I don't think that is carrier related at all, even my unlocked/international version only allowed 2g/3g in the second sim slot

Check that your APN settings are correct for your provider.
I would imagine sim 1 would allow 4g from any carrier as long as you have a 4g sim card/plan
I have a Huawei Mate 20 lite model using 2 sim cards. The problem I am having is that I can only have one sim card with LTE and VolTE option active. I need to make the other sim to have both LTE and VolTE option active too. Please any advise on how to fix this is welcome.
I did check if this is a sim card problem and I installed this sim card that cannot get active the LTE/VolTE in another cell phone and in that cell phone I was able to actived the LTE/VolTE. So this tell me if not a sim card problem and it is pointing to a device problem.
If this option LTE/VolTE can be active only in one the sim card, then I would like to know how can I make this change to the sim card I want to hace this option. I tried to swap the sim card and did not solve this problem. Please if anyone have any suggestion please let me know. Thanks.
If you have active LTE on that card and the option is not visible, ask the operator if this model is supported.
Also you can check in the developer options if you can select "lte on two SIM cards",
