[Q] [REQUEST] rSAP in Android (N1 controlling another device's sim)

My request is almost the exact opposite of this page,they want their cars to be able to use the rSAP profile on the N1,what I want is for the N1 to be able to connect to another device and use its sim. I have 2 T-Mobile sims,one has data,but no calling or text,and my other sim has voice and text,but no data. What I want to do it have the data sim in my N1 and leave my voice sim in another phone,and use the nexus to handle both.
Anyone have any ideas? I have a bootloader unlocked N1 running a rom that I pieced together from several roms on here that I can test on if anyone comes up with anything.

Tethering ?

T-Mobile Adding bigger data plans

So I just spoke to a friend who is a rep a T-Mobile, and he told me that they recently announced internally that they will be adding bigger and better data plans in the very near future.
He said the push is due to the 5gb limit being too low for so many users, and the 200mb plan being way too small.
Just thought you guys would want to know. If you ask any telephone rep at T-Mobile they will confirm it.

I knew there was a reason I was holding off activating my SIM. ;-) Any idea when they will officially announce the new data plans?

You can change the plan in the future. T-Mobile is less likely to extend the contract upon changing plan (except promotion one).

Ah that's a question I had, you can hold off on activating the SIM and still use the Streak 7 normally? I briefly had an AT&T tab and I could even use Google Maps without activation!

I am currently using my S7 with a non-activated SIM inserted. I can pick up a 4G signal, just can't use the data. Additionally, you want to have the cell radio working when you check for app updates, since the Android Market won't recognize certain apps if the cell radio is powered off...

Makes sense, have you tried Google Maps to see if does get some data like the AT&T did?

Not sure what you are asking, but yes, I can use Google Maps / Navigation, as long as I have data (WiFi) and the GPS radio is on. I have not tried Navigation with the cell signal...yet. Not really sure I want to pay for another data service, even if it is pseudo-4G.

Well like I wrote, on the AT&T Samsung Tab even without activating the SIM, data worked more or less, HTTP on port 80 and for Google Maps. Not sure why but it was handy!

I dont have a data plan and I disconnected wifi. I picked up a cell signal. I was able to do google searches no problem.. when I tried to click a link though it brought me to the TMO page to sign up for prepaid service. So maybe even without data the google things like search and according to you maps.. work. I was kind of surprised when I was able to do a google search with no dataplan and wifi turned off. For a split second I thought I was getting free data! Until I tried clicking on one of the links.. ahhahaha

Sounds a bit like what I'd experienced on the Tab than , I think Google News did work though, albeit slowly. It was certainly convenient for GPS guidance.

Ok, so let's test this further. I'll run mine for a few hours with just the cell and background sync and see if gmail etc work *without* an active data plan...

Sounds good and I'll be able to join you as my Streak 7 has arrived!

So, I gave it a try and no go, unlike on the Tab where AT&T let some limited data go through with an unactivated SIM, T-Mobile block out all traffic, makes sense.

Confirmed, although having the cell radio on does affect what apps you see in the Market.

I got my Ds7, when I signed up it said 39.99 for 5 GB, when I logged into my account, it says unlimited DATA, gotta love it.

That's a good deal! I've found that the 2gb/$25 of m ipad subscription have always been enough though.
@WookieFan - It also seems that GPS doesn't work in plane mode, even if activated with the smartbar toggle, is there a way to just turn off just the cell phone to try to save on battery life ?

That's because it's probably like most TMO data plans. It's 5GB of fast 3G/4G broadband data until you go over 5GB then it's EDGE speeds after that. It's still unlimited but just slower. Selling it as a 5GB and showing up as unlimited probably irks fewer folks though. They have done the opposite in the past. It doesn't matter to me either way since the end result is the same IMO. I do like how TMO does it. Much better than being raped with overages or cut off.

Not that I have been able to find. But I dont root my devices until the warranty is up. I suspect if yiu have root, you can get an app or a widget that will shut down just the cell radio. I can confirm that no widgets found in the market will shut off my cell radio on a stock S7.

I turned on airplane mode and tunrend on wifi and gps, all seems to be working.

Keep an eye on GPS, it stopped working the other day when I was using the same setup...and also when I wasn't in airplane mode yesterday so there might be other issues at play.

How do I make my Streak activated on TMO with a phone SIM card ?

If I delete the EFS folder, will a standard T MObile SIM card work on my Streak ?
Reason is TMobile will not activate data when it detects I have a tablet. I need a way to hide I have a Streak.

i have simple mobile which is basically tmobile and i used the sim with the tablet and the data worked just like on the phone. Why dont u activate the sim on a phone and then swap it to the tablet. am just saying it might work

Nope, that doesn't work. I have TMobile with data on my phone, when I swap my SIM into the tablet the data ceases to work.
I called TMO about this and they said I cannot use a SIm from a phone to work on a tablet, I need a different SIM with a Mobile Broadband data plan only.
I bought the Streak used, without a SIM.
I know some people on the Samsung Tab forum went through this, and they had to erase the EFS folder in the tablet so, it doesn't show the correct info when it connects to TMO.
Now I am trying to find out if I can do same with mine or maybe if there's a custom ROM that describes the unit as a phone instead of tablet.

I believe only samsung devices store their device data in /efs.
The streak 7 stores in a seperate partition, but it's binary data instead of a filesystem with files.

When I got this tablet I had to get a separate sim

If you email

They will give you an unlock code (about 48 hour turn around) - device works with about any active SIM card

I have an unlocked Streak 7 4G (bought it off of buy.com a couple weeks back) and I can confirm that you will have the same problems on the ATT network.
I tried 2 different SIMs and none of them would register data. I ended up having to spring for a (pricey) DataConnect plan and endure the petty sales pitch to go with an ATT branded tablet.
Unless there's something about the Dell unlock code I'm missing I do not believe it will have any impact on carrier filtering as carriers use the IMEI number to determine the device class (at least AT&T does).

i have a tmobile verion DS7 i can put my att sim card to it and use it as with out a tablet plan with ATT. when i call tmobile trying to request a unlock code they asked for my IMEI number and they wasn't able to find it on their system. i end up emailing dell to get the unlock code which they only ask for the service tag number. i don't think tmobile have my IMEI in their system. just something on the device telling tmobile it's a tablet. i even try to remove DS7 from the account online, but as soon as u put your sim card in again it will detect it

[Q] using nexus7 3g as a phone - is it possible?

i just bought the Nexus 7 3g (need to arrive in a few days)
i wandering if i can use it also as phone somehow with sim i have that include option to calls and data as well

There is a thread about this. At the moment it appears its not possible to make calls with it straight out the box. It "may" be possible to root it and sideload phonedialler apk, but people are testing this. You will be able to use your current sim (assuming its a micro sim) with the Nexus 7 for data (emails etc) though as the Nexus 7 is unlocked.

[Q] Dual sim adapter support for Nexus 6 (STK apk)

Hi everyone,
I know this is an obscure one and I may be the only one who wants this sort of thing but I live in the mountains and like to use T-Mobile but also keep a Verizon (PagePlus) SIM on hand with a cheap plan as sometimes I have to enter T-Mobile roaming areas and need more data than is allotted for roaming use.
Anyway, I have a Verizon Moto X (XT1060) and a dual sim adapter which works awesome (i.e., I can switch back and forth between T-Mo and Verizon service without rebooting using the Sim ToolKit (STK) app, which pops up when the phone sees the dual sim adapter installed).
I've installed the dual sim adapter in my Nexus 6 (Play Store unlocked version) and while the Sim Toolkit does seem to pop up once the adapter is inserted (and the T-Mo SIM seems to work still - see attached screenshot) it then crashes when trying to switch between sims and disappears from the launcher altogether (you can try and resurrect it via a "Activity" in Nova Launcher but it still doesn't work and just says the app isn't installed). In doing some research it seems like the STK apps in AOSP ROMs don't work very well (which might explain why this scheme works well in the Moto X) but I was curious as to if anyone has had any experience with this problem.
Since the Nexus 6 has such unbelievable cellular radio support across pretty much any network, CDMA and GSM/LTE alike, it seems like it'd be a great platform for the use of a dual sim system, which is why I'm kind of surprised it wasn't a dual sim phone to begin with...expecially since Android 5.1 is allegedly adding dual sim support but I think that may be mostly just a GUI to facilitate switching more than anything else.
I'm running the May 14 Euphoria 1.1 (OFFICIAL-20150514) with baseband MDM9625_104446.01.02.98R. I've tried a the .95 baseband as well, to no avail...and rebooting after switching SIMs doesn't seem to work either (and neither does just "waiting" a minute or two). I've also tried the stock ROM and it doesn't seem to work either...same sorts of issues. Finally, I should concede this might work better with a GSM / GSM SIM situation as opposed to a GSM / CDMA/GSM situation so perhaps it's a lost cause.
So yeah I just thought I'd throw this up in case anybody had any ideas on how to make this work.

No idea how, but out of interest, which adapter have you got? I'd like one.

Hi! I got mine on Amazon...XDA won't allow me to post a URL but the name of the accessory is "LOPURS 2 in 1 (Dual SIM Card Multi-SIM Card + Tray Holder) for iPhone 5/5S/5C(Dark blue)." Even though it's for iPhones allegedly it does seem to work ok on the Android platform as well (at least, on my Moto X).
It's definitely weird looking but with a case around the Nexus it seems to fit alright.

Here's one for the Samsung Galaxy S5 on Amazon, but seems there's quite a few different ones to choose from:
http://www.amazon.com/LOPURS-Adapte...6-6747327?ie=UTF8&refRID=103H6N95BRG8HE3ZM64C

Curious with the 5.1 update if this will work natively. It's been advertised that dual sim support is built into 5.1.
What's your experience? Any updates?

Unfortunately the adapter doesn't work with 5.1 or 5.0...one is able to launch the 'Sim Cards' activity (this gets you to the new SIM Cards settings menu in 5.1) via Nova Launcher by setting up an Activity widget but since (I think) the adapter can only work with one SIM at a time (it seems to block one or the other altogether depending on which is selected) the new functionality in 5.1 appears to not be useful in working with the adapter...I think it'll only work with phones that are dual-SIM by default.
I accidentally destroyed my last adapter (they're extremely delicate, and are hard to install with SIM tray-type phones) so I'll try this again once I get a new one using the Android M developer preview...fingers crossed!

Thanks for the update! 'Preciate it.

So...this can be marked resolved. It turns out that the Nexus 6 accepts the dual SIM adapter just fine (takes a reboot or two, but it eventually settles in and works great) and I successfully used it with two T-Mobile US SIM cards. The issue was the Verizon SIM containing some sort of CDMA code that was (I'm guessing) fouling up the changeover and crashing the adapter's firmware and/or the STK app. The odd thing is that it did work on my Moto X XT1060...but after trying again I noticed that voice support never actually worked on the Moto with the SIM adapter installed (nor did eHRPD or 1X data - only LTE worked) so it appears that CDMA just isn't compatible with the adapter(s) I've been using. I did see that MagicSIM offers an adapter that's allegedly compatible with CDMA but I'm a bit skeptical honestly and these adapters are just too delicate to spend $30-$40 on.
So, in conclusion, this functionality is absolutely do-able but it requires two GSM SIM cards as opposed to one GSM and one CDMA/LTE.
In any case it'd be totally awesome if LTE/CDMA-GSM changeovers could be accomplished with a different adapter...so if anybody ever has any luck with that please post! Thank you for the replies.

With the GSMx2 sims, how much functionality did you get? Could you receive calls on both numbers? Did you get a prompt when dialling which number to call from?

Unfortunately you only get very basic functionality. All the adapter is capable of is switching between the SIMs...once it's switched to one or the other it can only see that one SIM. You can set it to automatically switch back and forth in time intervals but I bet that can get really annoying sometimes if you're in the middle of a call or web browsing session or something...not sure if the adapter is smart enough to know not to interrupt a call or download with a switchover...I bet not!
I know that actual dual SIM phones can do what you describe but unfortunately none that I've been able to find have the vast frequency support of the Nexus 6 so it's kind of a conundrum...I really wish Google had made the Nexus a dual SIM setup...big missed opportunity IMO.
But in any case the adapter can help if you're a frequent traveller or have a work and personal phone or whatever and you don't wish to swap SIMs all the time...or if you're like me and just need two carriers to fill in each others' coverage gaps and can use Google Voice to route your main number to both carrier numbers.

That wouldn't be too bad I suppose as long as a reboot isn't required. I forward work to personal anyway and just turn work phone on when I need to make a call.
