I know that we cant use both sim at sqme time
But the 2nd sim should resume his work automatically after the end of call from 1st sim right? Mine did not work at all till i restart or just activite and de activte the air plane. Mode.

I've got two sims also. Tell me what setup you have , I know you mentioned sim one is for calls and 3G? And sim 2 is for data only? I don't see an option on here. I have a global setting for 3g 4g 5g etc and then I also have a default option to state voice or data for each line as a preference.

Rebel Simcard Stopped Working... :(

I just got my streak this morning. I inserted the rebel simcard along with my simcard.
Voice calls were working, text messages, voicemail, etc...
I noticed a few hours later that it now displays NO SERVICE...
I tried everything, rebooting, taking out battery, taking the rebel simcard out and putting it in again, still says no service.
Any ideas?
Thanks in advance...

Have you done everything it says on the rebel Sim forum there is a video and a section on there with lots of answers and do a google for your problem chances are some one has come across your problem before
I checked out the FAQ and it said to keep ROAMING DATA ON.
It WAS on at first when it was working but I turned it off since I do not use it and have to pay 50 pence everytime I connect to it!
Keeping roaming on will charge me £14 per month!
Hopefully soon they will find a way to unlock it properly, but annoying that I MUST keep roaming ON otherwise phone will not work...
my rebel sim ii doesnt work that well either - I am on optus in australia. I need an unlock code. Hopefully it will come thru when it gets released in america and china.

It SHOULD work. However, you have to use it in a certain way.
The Rebel sim wasn't working for me either until I followed a guide.
After I followed these instructions, the rebel sim card now works...
What you have to do is:
1. You need to place your network sim in a 2G only phone and let your simcard get network.
2. If using a 3G Model phone turn off 3G and then get network on your sim in 2G mode but this does not work for all phones as some phones even when you turn off 3G in the software functions will initalise your network sim in 3G/UMTS Mode but we need to initialise the network sim in 2G mode so try another model phone to get network in 2G then use in Dell Streak if you cant get network at all that is the reason.
3. Place in Dell streak but first make sure Dell Streak Data roaming is turned on and 3G is off
4. From Time to time you may loose network when travelling through network black spots but when stationary its not a problem.
5. When you loose network the only way to regian this is to place your network sim in a 2g only phone or a phone is 2g mode as described above and then enter back in to the Streak.

Yes i do this.but the 5 point is no good.my provider work only in 3g mode.my provider is 3.if i put in 2g mode work but i dont have data connection.
Ah ok, it's a shame...
I do not use 3g so it's not a problem for me but it's a problem at the moment for those who do!
I just looked at my phone and it now says ''no service''
One day it will work, the next it won't...
It's really pissing me off.
The rebel simcard is really unreliable, what a waste of £10...
I really do need to find a proper way of unlocking it.
I now have a phone that does not work.
Anyone have any suggestions?
This is a temporary but annoying solution to get your rebel sim working again...
I've done this for the THIRD time in 2 days...
After a few hours or a day of using your streak with the rebel sim, you will suddenly notice emergency calls or no service...
Regardless of what you do, turn your phone off and on or even taking out your simcard and reinserting it will not solve the problem.
The only solution is to get a spare phone, put your simcard in it, manually specify your network, then put the simcard along with the rebel sim back into the dell streak...
It's really stupid that I have to do this to get reception, should I of known this I would not have bought the dell or this piece of $hit rebel sim card which doesn't work properly for most people...

This has been working now for me for the last 12 hrs
Sent from my Dell Streak using XDA App
Cool, glad you got it working!
Mine has been working all day so far, around 12 hours so far, I hope it stays that way!!
ok this morning I noticed I wasn't recieving SMS's or Calls - so I rebooted and it fixed it FYI
Nothing against the method that was devised - but this phone caught me out again whilst I was out and about and dropped connection to calls / sms and 3g all at once and totally screwed me. As a result, I'm putting it back in the cupboard and getting out my G1 until an unlock code is released.
I dont understand why dont exist unlock code for streak.its impossible find other method for code?
I'm unsure why it works for some people and others it doesn't...
However, yes, it's best to get an unlock code as it will permanently work & all features/functions will work...
My Streak may stop working soon as well, who knows...
But try to do it again as I have.
I have had my streak for only 3 days and 3 times it suddenly stopped working and I got no network and I had to get another spare unlocked phone and follow the previous instructions.
Try the instructions again and see what happens.
Hi
Looks like all are using older v1.1 firmware that has some issues with Dell Streak.
However the the newer V1.2 that was released fixes anu kind of issues with signal loss

Can't make calls when on LTE mode

I have n9005 rooted TouchWiz stock on 5.0,
when my phone is on LTE mode i'am unable to make/receive calls.
Kindly help me solve this problem.
Is the phone set to LTE only? If it is, does the carrier support VoLTE?

LTE/4G is a Data-Only network. To make calls over it your carrier needs to support Voice Over LTE, or VoLTE for short. Which is the mobile equivalent of VoIP.\
If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can't make calls. Change to 'LTE/WCDMA (Auto)' (4G/3G) or 'LTE/WCDMA/GSM (Auto)' (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

Something appears to be preventing the automatic switch from LTE to 3G/2G. Did you do something in the Servce menu?

My device didn't had the LTE option first so i did something which i don't remember now, what it was, i did it when i never used LTE, but as now i'm using LTE and came accross this problem. also i have installed a network type toggle app.
Sorry for being such a nub but where do I go to change the mode? Option > network operation? Thanks

Not receiving incoming calls on AIRTEL 4G LTE
Iam facing peculiar problem with the phone. Need help with the problem.
I am using samsung note 3 LTE. When ever some one tries to call me, my mobile is Not reachable or out of coverage area even when my mobile is in my hand , perfectly working with the second sim. outgoing calls are working fine. Again, when I am in call, then if any one tries calling me, then I get call waiting. So incoming call waiting is working for me. But incoming calls are not able to connect. LTE data is working fine though incoming calls are not working. 
Tried the following but no luck. Problem still persists:
1. Reset phone and erase all data
2. Hard reset phone (volume down + poweroff and clear all data in drive)
3. Tried changing SIM to second slot
When I switch the sim back to 3G mode or 2g mode , incoming calls are working perfectly fine . I googled it and found that most people had same issue and was resolved on switching back to 3G or 2g . 
But I need to use 4g . Please tell me a solution.
I had that same issue until I took my note 3 to Rogers and they said that the note 3 doesn't support Lte
Your rom must support VoLTE.
I would unroot and go back to stock firmware, and see if problem still happens,? if it does ,its most likely the sim card.sd card reader slot, (flex cable),my Galaxy s4 had the similar symptoms , but LTE would work with a custom rom, but not if I used stock firmware, replacing sim card reader flex , just google your mak and model and search ebay. mine cost a few pounds for a decent quality part, so dont go rushing to buy the cheapest. No problems since replacing that part, even after resetting phone 3 times to see if it was a fluke. I know its a bit late for a reply, but this actually worked , I am 99% sure it would work for anyone else who has this problem with lte not connecting when 3G, and 2g do connect. If you have tried swapping sim cards, putting sim in another phone,, etc,etc. this part mentioned(sim card/sd card reader) is your culprit. Took me just over 5 hours of testing to find the solution. thanks and fair well android users

For many people having issues with LTE not connecting and diverting to voicemail on android, I am here to offer a solution to your woes. I have a Samsung Galaxy S4, GT-I9505, and recently in in 2018 in July, I had the same problem, phone calls connected on Gsm, Wdcma, BUT when I tried LTe mode, NOTHING, WENT STRAIGHT TO VOICEMAIL.Anyway I tried almost everything mentioned on certain websites and forums, with some luck, Changing LTE mode to GSM worked, and I could receive and hear phone calls. So I investigated further, I tried re flashing stock firmware, factory resetting phone.(nothing worked). I then rooted my phone and flashed a custom rom (do not try this) as it could damage your device if flashed wrongly. Yeah, so I flashed a custom rom, and low and behold problem disappeared, so I used my phone on LTE for 2 days, with no problems, I then decided to go bacjk to stock firmware, ...problem came back, not connecting to LTE mode..........being as patient as I can be, never gave up, and had a spare phone which was dead, just laying in the drawer, ..so ,I took phone apart and thought, it must be where simcard contact make contact with sim card reader contacts ( broken sim card /sd card reader part, and was I wrong, no, it actually was the sim card reader part which coonects with th motherboard, Voila, I am 99% sure if anyone else has this problem with any android that has LTE capabilities, and you know its not the sim card, then try this fix first, MAKING SURE YOU GET SOMEONE YOU KNOW TO HELP YOU , IF YOU ARE UNSURE OF WHERE TO BUY AD HOW TO FIT. hope this has helped,and I know it is a long thread, but hopefully it will be a solution that works for whoever reads and trie this, over and out. yours in sincerity, Tech82, from Surrey, England.

Where it is actually the sim holder .
But 99% of the problems are not the sim holder .

*DUAL SIM* LG V20 users: Please test 4G/3G capabilities and report your findings...

Hi guys,
For anyone with a dual SIM model of the LG V20, can you please do myself and others a big favour?
I need to determine the phones capabilities and functionality when it comes to dual sim capability. We know this is only dual standby, but I need to determine a few things. Can someone please answer these questions ONLY if you have this phone and ONLY if you've tested it?
1) Can a 3G phone (voice) call be received on a SIM whilst the other SIM's 4G data is in use (Y/N)?
2) If yes, does the 4G data SWITCH OVER to the other SIM to allow that voice call to come through, or:
3) Does the 4G data temporarily cut out on the "data active" SIM for the other SIM to allow inbound 3G voice call?
4) Can you deactivate test to confirm with 100% accutracy only 4g and/or 3G is being used on both SIMs?
Any help from current users (or if anyone can post a video oft he settings/functionality), that would be awesome!
Thank you

Hi. Cant exactly verify this because in the Phillippines H990DS. We dont have voice call over 3G.
But if it helps, i have a viber account on SIM2s number. I use SIM1 as Data provider.
When i get a viber call on SIM2s number, it doesnt switch but instead uses SIM1s data.
But not entirely sure if that works the same as Voice over 3G
When one sim is in use the other is disabled, I think the only phone that does this is huawei mate 7, but that's 4G+2G or 3G+2G.

Not entirely. Yes, they are dual standy by...but when 4G is active on SIM and call comes in on SIM 2, it should eityhert SWITCH the data to SIM 2 to allow call to come through, or temporarily disable 4G on SIM 1 for the call to get through. See other models that dpo this:
http://whirlpool.net.au/wiki/dual_sim_4g3g_phones
This phone has the new chipset that can allow this. Have you actually tried this, or have any images to confirm your findings?

You have the HK model, right? Makes no sense why two dozen or more other models out there with this chipset can allow 4g/3g (evenif 1 is temporarily disabled) and this new flagship doesnt.
i got the H990DS today. I have Tmo and AT&T. it has 3G standby. No matter which SIM i select in 4G the other always holds 3G.

..
here is my findings for a few days, i bought a data sim card (only internet) and added to my LG V20 as SIM2
1) yes, you can receive calls while the data is working on the second sim
2,3) in my case, when i receive a call from SIM1 (4G), the data SIM2 still connects between 4G and 3.5G, but in both cases the data is been cutted off and unable to do anything
(this was tested via hotspot the SIM2 and getting a call on SIM1, happened multiple occasions)
4) until now, SIM1 and SIM2 in my device works both on 4G (battery drainage is surprisingly holding up)(tested via switching between SIM1 and SIM2 Data connection)
one note to be considered, the data speed was very low, i called my provider and adviced me to switch to another device (portable router adviced), i switched the sim to another device (Note 3) and the net speed was signifacantly better for a while

Your answer is helpful, Silver Mask! Just to confirm, if I'm on a call on SIM2, I would not be able to use the internet on SIM1 at the same time? (e.g. if I wanted to use Google Maps with SIM1 sata while I have a SIM2 call on speaker). If I understand correctly, you're saying I can receive a call on SIM2 while I'm using SIM1 data but once I pick up the call, the data from SIM1 will be temporarily disabled?

Either disabled as an extream case, 50% of the time it switch to lower band (from 4G/LTE to 3G), even then the data feels slow, but usually any navigation app and social messaging apps doesn't get affected that much, it is just annoying

Data with 2 sim ?

Hello,
i hesitate to take a second sim, but my interest is not to call but to have data.
Do you know if i can use data with sim 1 and sim 2 in same time, or the sim 2 is just to have another phone number and not specialize for data.
I have search, and it seems tha the sim 2 is not in LTE for the data but only GPRS/EDGE, that does not really interest me, does someone has test that ?
Thanks

4G Data works on both SIMS! The SIM where data is enabled will automatically switch to 4g/3g/2g and the other SIM will revert to 3G/2G. There is no restriction on where you wanna use 4G.
This is same with most of dual SIM phones as of now.
Thanks for the explication.

There could be 3 possible ways.
1) Software bug
2) sim slot pin breakage
3) sim card chip problem
Identify the root cause at first.

Can you provide more information.
Are you on 4g network.
What type of error do you get.
Your circle.
Have you changed your network settings using *#*#4636#*#*?
Have you tried calling using 3g and 2g only?
If not choose WCDMA only (use above code). Also try with GSM only.

Same problem here. Solution for now is to change to 2G network, at least for me. When I try to call with 4G preferred sometimes it work, but when it works they can't hear me and I have to scream. This Pie update have so many bugs it is ridiculous. I can't believe they put such ****ty update to the masses it seems like BETA version. In Oreo when making call phone switches from 4G to 3G instantly now in Pie switches worry slow if it even switch and the signal is so bad that the call drops and that is in places where the signal is perfect
