[Q] HTC Desire 816 dual - Desire 816 Q&A, Help & Troubleshooting

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.

Internet working Mobile Phone not.

Hey guys,
So this might be a simple problem, then again it might not but as described the internet works but all mobile activities do not.
I see an x by the normal reception bar so i tried to manually assign a network to my phone. Upon selecting 02 - UK it says:
Your SIM car does not allow a connection to this network.
I have tried the sim in another phone it works, i have hard re-set, soft re-set tried auto selecting the network. I am at a bit of a loss as to why the phone won't work now.
Any ideas at all?
Cheers Jamie
is my question that boring that nobody has a view on it or is it because nobody has an answer.
I'm being impatient because its rubbish not being able to use my phone as phone.
You should ask your mobile operater and insist on a new sim card.If I were you,I will do that.
BTW,did you tried other SIM cards in your phone?

o yes, sorry forgot to mention that. I could make calls from my old mobile. Seems very odd to me seeing as the phone is blocking my from picking a provider yet not stopping my internet access?
Order a new sim card from 02, what's happening is that you probably have an outdated sim card and it does not provide data services support. When you receive your new sim card, go to the 02 website, transfer your old number it your new sim card it retain it. Then you should be good to go.

[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] "Emergency calls only"

My Zenfone 2 always shows "emergency calls only" on the lockscreen and in the notification pulldown even when there's a working SIM in.
I'm on Vodafone UK.
Is this the same for everyone?

Rowbaggie is correct, when you put a sim card into a phone, there are 2 processes during this time
1) handset check the network and perform LU ( location update)
2) if it succeed, then it will pull out all profile details. the SIM card by default would have the postpaid, prepaid 3G, 4G APN in it.
by default network will automate append this APN so user does not have to set it ( unlike wap services)
my guess is that your APN got screwed up, you can go to your service provider website and check for the correct APN to use.
Or call them up.
By the way, APN is also known as Access point in 802.xx. in 3GPP standard it is call APN.
Thanks guys...but my api settings are correct. 3G and 4G works fine.

are you able to try this sim on the 3G/4G slot?
lets test it out to eliminate sim slot failing.
perform single sim one 2G first
then perform single sim on 3G/4G
post the result,
next try to put Sim A to 3G/4G and sim B to 2G slot
flip the case and post result.
sound like sim card is not attached to network properly. could be sim loose from slot. i can be wrong.
Ok last night I took sim card out of my phone,its Asus zenfone. Now today the phone won't even read the card ,what do I do?

Dual SIM with Freedom Pop. Is it possible to force Whastapp to use FreedomPop SIM?

Hi,
I've a Dual SIM phone (Oneplus 3) and I'm thinking about getting the FreedomPop Basic Plan (the free one) which offers 1GB for whatsapp data.
The thing is that I would like only Whatsapp using data connection through that SIM (even with 2g velocity) while other apps use my main SIM, so I can save the 200MB just in case I run out of MB on my main operator.
I've not found any app that can do this on Google Play Store (there are only apps to choose set a default SIM depending on the contact you want to call.
Is there any apk that can do this? Or some way to develop it?
Thank you!

No its impossible... you have to choose in settings which sim is for data... You cannot get 2x data's simultaneously ... Its either sim1 or sim2

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
