Hello,
I have a Samsung Galaxy S without a data-connection, I really need a data-connection becouse I think the phone really needs a data-connection.
So here's my question:
Is it possible to get a subscription of a data-only SIM (the subscriptions they use for tablets etc.)
It is possible to use that kind of SIM/subscription in a phone?
Since I don't really make calls or send text's I really need that but I still want to be able to call and send text's.
Does anyone got a answer?
I think it would be helpful if you told us where you're from. I'm pretty sure the conditions for data-only plans differ from country to country.
I'm from The Netherlands.
Data only sim should work fine. Curious to know, why you need data only sim on a phone. It kills the purpose of having a phone.
I tried some time ago in HTC Desire and it didn't work, still don't know why. (it works with PC + USB Huawei modem on both Windows and Linux, i have E1752 model)
And as an answer for qustion "why do you need it?" for example in Poland there is company which for the government licence for some frequences is obligated to offer free internet for 3 years. Don't think its lika a fairytale - internet disconnects after one hour and the speed is limited, but still can be very usefull when you are tight on budget or just need to check something quickly.
PS. maybe i should add that in this case voice service is disabled on the sim card level (tele service (ts11)) what seems to be a reason for some devices not to work.
edit: finally it appears to work. Dosen't display signal strength but websites (slowly) load.
Hello everybody,
I'm using a SIM supposed to work in a normal mobile.. I have normal calls and All-you-can-eat internet on that SIM..... This SIM worked perfectly the first 2 months ... but know it detected that it is used in a TABLET... and as this tariff is not designed for TABLET the SIM got locked!
I spoke to the provider and they are offering me a broadband SIM but with this the normal call charge is much higher!!
Is there any chance to modify the ROM in that way that it identifies my N8000 as a mobile phone and I can use the normal mobile tarife?
Please let me know .. that would be very helpful
regards

Probably not as the carriers note the IMEI of the phone/tablet you are using.... The IMEI is tagged on any calls you make from the device you are using.
Only thing I know is the user agent from the browser. On tablets its changed to tablet. This could be investigated from the provider.
Take a look at this. Maybe its so simple.
So along with my recent phone upgrade i needed to get a new dual sim adapter. Went with another from www.magic-sim.com and its working great for me. Personally always had a great experience with these little devices and can recommend them! :good:

Had one for the S4 that stopped working after a while, needing a reboot every time you wanted to pick up signal.
I agree with EnricoIT i had the same problems...
Always had great experiences with these devices personally too, in the past when i've needed any technical help their customer service has always been great.
Does anyone no if it's possible to use data from one sim and phone from the other, at the same time. My work Sim doesn't have data, so I'm constantly tethered to another phone with my sim in it. (WiFi doesn't work well in my workplace)

Surely not. Not until there is a true dualsim version of S5
anyone care to discuss use of the s5 with dual sim adapter? is it simple as pop it in and go, or do you have to manually switch from one sim card to the other? I have a crappy work phone and an s5 and would like to just put the work sim into a dual adapter and carry just the s5.
There is a duos version of S5 (SM-G900FD) like this one that I'm using. They are sold in the middle east, mine is a UAE version but I live in Singapore. Everything is mostly the same except the extra sim slot and its unlock.

I'm performing research into an odd issue that may affect custom ROMs across multiple devices, and I'm hoping a few people can help me.
If you're here, you probably know that Sprint is a CDMA carrier. The SIM card is for LTE only, and so removing it should not affect ability to make calls, and the phone should still get 3G data just fine.
On my stock Lollipop Note 3, it works as expected; a notification bugging me to insert a SIM, but otherwise works fine with 3G.
I had a Samsung rep take the SIM out of his Sprint Marshmallow S6, expecting it would work the same... but instead it completely killed the cell radio. No connection at all, no phone calls, no Mobile Networks option in Settings.
On ports of Note 5 firmware, the phone will connect to the network for phone calls, but absolutely not allow mobile data to turn on. However, this seems to be because the source ROM is GSM only - the Sprint kernel and modem allow it to use CDMA, but the UI still can not fathom having mobile data without a SIM and simply disables the option. The same happens with an S7 ROM port (also from GSM-only source). With a lot of command line %&$#ery, I managed to make it use 3G, but only for about 10 minutes before it catches on and the phone has to reboot.
Now the question I seek to answer is whether the ROM port issue occurs because the source ROM was GSM, or because Samsung just removed the capacity for CDMA-only data from more modern phones. Once I know that, I can work toward fixing it. As such, I humbly request that a few people boot their Sprint Note 5's on stock(-ish) firmware without a SIM card, and let me know if they can use 3G like that.
Cheers! :fingers-crossed:
Newer phones have different hardware. The S6 and Note 5 need the SIM card to authenticate with LTE and with CDMA/EVDO. A rom change will never fix this. This is the next way phone manufacturers and Sprint want new phones to be built. The CDMA and LTE are one authentication.
Your Note 3 had the old way of authentication, where the CDMA portion was separate from LTE. Hence, when the SIM card was removed, 3G worked because the CDMA authentication was embedded into the device.
New phones will not allow this, and honestly, the only reason you were able to use Sprint CDMA without the SIM card is because Sprint has your device ID and let it authenticate for a bit, but then the network itself rejected you because there was no authentication mechanism.
That's... all really a wonderful theory, but the whole point is that current research is indicating it doesn't work the way anyone thinks it does. Even the Samsung rep was shocked that his phone behaved the way it did.
As of right now, I have located one Marshmallow ROM that will allow 3G to work perfectly without a SIM, but have not heard back from the dev on how; it's based off CM, which in my experience will not. The ROMs that don't, don't stop because of authentication issues, they stop purely because of a UI trigger. Otherwise just rebooting wouldn't allow it to be fine for another 10 minutes.
Hence, research. I know all about what it ought to do. And why, and how. I could write a paper on it. I want to know what it does. For that, I ask only for some kind soul to boot their phone without a SIM for two minutes.
That's because its not a theory. It's reality.
In a cdmaOne/CDMA2000 ("CDMA") network, the UICC contains a CSIM application, in addition to 3GPP USIM and SIM applications. A card with all 3 features is called a removable user identity card, or R-UIM. Thus, the R-UIM card can be inserted into CDMA, GSM, or UMTS handsets, and will work in all three cases.

I fried my SIM card when I first got the phone by using QPST to try to flash a custom PRL. Not only did the phone power cycle every 5 minutes, but it lost its entire connection to the network. No 3G, no LTE, no 1x. When i went to replace the SIM card, the rep went through about 5 cards until he found one that was actually a UICC card, as the others were ordinary SIM cards just for LTE.
Also, please don't tout research on XDA. Your research is at best an observation with one ROM, and my guess it was a fluke where Sprint didn't reject your connection. Research requires actual proof and peer review. One ROM working one time doesn't warrant research. This isn't an issue with a "UI Trigger" as you put it, but its just the new way phones are authenticated.
Try removing a UICC card from a recent Nexus device (6,5X,6P), it will lose all connection as well. Why? Not because of a UI Trigger, but because new phones need the UICC to authenticate both CDMA and LTE.
Finally, unless that Samsung rep was a Samsung engineer, he is just a salesman with little tech knowledge past what is needed to sell the device.

Similar issue with HLTESPR (Sprint Note3) moved to Lineage OS 5.8.2 can not make calls with SIM card inserted. Remove the card and the 4 works fine (no LTE). APN and Carrier show up in settings.
Replace the SIM card no APN's no carrier, no phone unless on WiFi.
Hello, there is a common USA Issue. pretty much every phone which is not sold through the provider lite ATT / Tmobile etc all the Phone features like VolLTE and WIFI Calling are not possible and locked.
A sim Card in one of their phones works. Using any of the XIAMOI i.e. or phones all the features work with any provider other than the US ones. Is this something where they

Because the US devices are carrier/SIM locked unless the device is unlocked using the device's/carrier's specific unlock method. As far as I know, Volte and Wi-Fi calling are setup and regulated by the carrier from their end, not on the user end.
Well I think we missunderstood a little SOme us Devices especially ATT are "SIM" Locked this is a total different avenue .
I am talking about WIFI Calling. Szenario :
I have a us SIm Card WIFI Calling VoLTE in US Phones Iphone and the few Androids (99% Samsung) they sell working fine
I use a European Phone works fine with almsot any provider (WIFI Calling and VoLTE) in most phones from euopr and the US phones as described above.
Use Teh US Sim Card in one of the EUropean phnes every thing works in terms of Data and VOice,Text but "NO" WIFI Calling od VoLTE . WIFI Calling is not even showing up.
My question is as simple as it can be "WHERE" and what technology swith the features on and OFF ? It must be recognized by the IMIE Number or IM Wrong ?
