[Q] Data features on the HTC M8 dual Sim

Dears,
Am in the process of researching/buying an HTC M8 dual SIM phone, can someone please advise if it is feasible to STOP Mobile DATA on a certain line (Ex: Line1) and ENABLE Mobile Data on the other line (Ex: Line2).
Thanks for all your help.

Bad dual sim management
Better late than never, right?
You find "dual sim management" in the phone's settings.
This is where you can activate and deactivate each sim and where you set the preferred sim for mobile data.
So, yes, you can easily switch the sim that's being used for mobile data.. However, the BIG restriction is, that the sim 2 radio only supports 2G (up to EDGE). So, in order to use high speed internet from the provider whose sim is located in slot 2 you actually have to swap the sim cards. Also, there's no way to automatically switch to the other network's mobile data in case you lose mobile data coverage on the preset network . You really have to tell the phone manually which network to use.
Another big issue for me is that I can't preset the network I use for calls. So, my sim 1 is for data only. sim 2 is for voice calls and texts. Remember: it has to be this way because only sim 1 supports 3G/4G. Now, when I initiate a call via voice or via my car's bluetooth unit the phone automatically tries to use sim 1 as the default for calls. I can't set it up to use sim 2 as the default call handler and there's no dialogue asking me which sim to use like when I dial manually. That's really bad, all other companies that offer dual sim phones have better management options in their software's settings.
I tried using alternative phone apps which give you the option of choosing a default sim for calls but this only works for voice-dialing; bluetooth still overrides the alternative dialer and always goes with the stock one.
I hope this helps - so actually I'd advice agaist the M8 dual sim despite it being beautiful and having really good hardware.

[Q] HTC Desire 816 dual

Hi everyone.
It's m'y first experience with Android on HTC device. I have two number with data plan so I want whether it's possible to switch between the two sim cards to go on Internet and how to do it.
Thanks

Only the first Sim slot connects with 3G so there's not much of a point for using snail paced data on second Sim.
that said, you can easily change "preferred data network" in "Dual Network Manager" section in settings.

Thann you for your seekfind but I don't have the option to choose a preferred network.

I don't know about 816d variant but generally 816 has this option in settings>Dual Network Manager. at the same place there is an option to turn on and turn off your sim slots. also, have you setup your Access point names(APNs) correctly for each sim card in mobile data section?

Yes the APN are good and I use both of them for internet, but for now to use internet with the second sim, I turn off me first one so I can't receive call anymore. My friend has a LG dual Sim too but his phone has a function to do it easily without turn off the first slot, maybe it's the same for HTC but I don't know how activate it.

Dual SIM Data issue: after reboot always on wrong SIM

Hey champs,
I got a strange issue with the swift. Last year I bought 3 Swifts for my wfe and kids. All of them equipped with two SIMs (1&1 for wired phone connections only, Simyo for cheap data flatrate and calls to mobile phone numbers). All phones have been upgraded to Android 6 so far. We use dual sim selector pro to do the call routing to the correct SIM, works like a charme. But regardless what I set in mobile data settings, after reboot the mobile data will always connect to 1&1 mobile networks (in fact it is vodafone) giving us one time a very high bill.
In the meantime I amended the vodafone APN to get rid of it, but this only leads to the situation, that after a reboot there is no mobile data at all. And since my son's phone is locked by funamo parental control, he is even not capable of swithcing mobile data by the settings.
Is there any chance to make the setting permanent? Is there any API call available, so I can get it managed e.g. by tasker? Is there an app available, that deals with data settings on dual SIM phones with Qualcom chipset?
Tnx in advance!

Glad to see I am not the only one with a problem, I live in Spain and use Orange SIM for data and voice, I also have a tesco voice only SIM which I use when in UK. Fine. I have exactly the same problem after a reboot or flat battery, "No Data Connection" when I check the settings it has changed to Tesco (which does not have data) Its only the data scource SIM that changes - voice and SMS remain as Orange. It is very annoying.

Same problem here with stock Android 6.0.1 Cyanogen OS 13.0-ZNH0EAS2NH and EE sims in slot 1 and 2... (one work and other personal).
Was thinking of returning phone, but apart from this problem, I really like it.

Latest Cyanogen OS update, (just installed), appears to have fixed my problem...
I updated, did a battery pull just for good measure, and with several restarts, the correct SIM appears to be selected each time.

Dual SIM

Thinking of getting a 5T (or maybe 6 depending on timing) and have never had a dual-SIM phone. I would have one SIM card for my U.S. Cricket account and use the other slot for a pay-as-you-go "travel SIM" for use in Europe.
So are there settings or a built-in app provided so that I can activate one card at a time? I know it's possible to have both in "standby," but that's not practical in this case since I wouldn't want one of the cards causing the phone to be searching for a tower constantly -- a real battery-killer. I also would want to be able to assign one or the other for data, etc. (The particular travel SIM I have in mind will actually work in the U.S., but then I'd be paying per call, text, and data chunk).

You can enable or disable each card independently. You can choose a default SIM for calling, messaging, and data. The built in messaging app also lets you choose what card to send from with a convenient button in the text entry field. I have attached some screenshots that show the SIM options in the settings menu. I've been using dual SIM for a few days now and find it very easy to manage. Hopefully this answered all your questions.

Perfect answer. Thanks!

Secondary SIM Mobile data

Currently I am not able to find the option to use the mobile data for secondary SIM as well.
As I checked the options, we are only able to use the Mobile data of primary SIM which is a bit irritating because I was able to do it on my 2 year old one Plus 3T.
Does anybody know the option by which I can use the Mobile data of secondary SIM card without swapping the SIM cards manually?

Go to network setting and then sim cards and then data sim.
Select whichever sim you want
