TMobile *T 5G converted to Global and updated to the newest OTA.
I purchased a dual SIM holder on EBAY and while the phone now does detect both SIM cards, it will not allow me to use either of them. Separately they work fine, but once I put both SIM cards in the phone, both mobile data and phone service will cut off and a warning will pop up saying SIM 2 not allowed. The SIM settings screen says both SIM are active bit i no longer have data or phone service.
With both cards inserted and one of them de-activated then the other will work. I am new to dual SIM usage. Is this normal behavior? Maybe since there is only one IMEI for both slots, could this be the reason both cannot work at the same time?
Yup, I believe you are correct. There is only 1 IMEI so effectively DSDS vs DSDA. Standby vs Active.
Question for you actually, I purchased a DS from Amazon and it did not slide in all the way. Both SIMs were recognized, but I didn't want to kill the IP rating. Is your purchase the same, if not, can you send me a link to the version you received. Looking to get a silver version for my Global T-Mobile Conversion.
Thanks

I recently purchased a used Motorola Droid Ultra to replace my current Droid Bionic. I am on Verizon and went to the local corporate store to obtain a nano SIM for the Ultra. The SIM provided was not NFC and when I went on-line to activate with the Verizon website, I received an error that the SIM card was not compatible. I ordered a new NFC SIM from the website and am awaiting its arrival. Here are two questions that I have concerning the new NFC SIM.
1. Once activated in the Ultra can the NFC SIM be removed and activated in the Droid Bionic using a nano to mini SIM adapter? If so, can I just swap the NFC SIM or do I need to go on-line and input the MEID and NFC SIM ID? By the way, I do realize that the NFC SIM would not give the Bionic any new powers with relation to NFC.
2. Is it possible to leave the old mini SIM in the Droid Bionic and simply reactivate using the Verizon Website for times that I want to use the Bionic instead of the Ultra. I have read elsewhere that there is some kind of deactivation after some time period whereby the old SIM is dead and cannot be reused on my account or any other account. Does anyone know if this is true and if so, what are the timeframes?
Thanks, in advance, for any help on these questions.

"NFC SIM" just means it's got a NFC secure element on it, to facilitate Isis payment transactions.
Otherwise, swap it around at will. I do both Android and iPhone development at work and I'll bounce between an iPhone 5 or my Droid Maxx depending on what project I'm working on that day. I routinely swap the (NFC-enabled) nano-SIM between my Maxx and my iPhone 5 without trouble, so I can't imagine why you'd have any trouble with an adapter in your Bionic.
I believe they have fixed the deactivation period issue. I know when I did some device shuffling on my account even a year ago, it seemed that if you "deactivate" a SIM, it's put on hold for ~24 hours, and then after that point it can be used again. That was contrary to my experience back in 2011 where it was most definitely the case that if you deactivated a SIM it was pretty much burned for good.

Thank you for this information. This was what I was thinking but have not tested the NFC SIM in the Bionic. My understanding is that it is basically identical to a standard nano SIM with some extra information to support secure NFC transactions via Isis wallet.
I did determine that I can continue to use the Bionic in WiFi mode both with and without the old SIM card installed. If no SIM is present, you get a warning on bootup and can then function as usual on WiFi. With the SIM installed, it shows network strength but, of course, no calls or data. I am interested in leaving the card in the Bionic because it is a booger to swap. It requires removing the back, the battery, and SD card to just get to the SIM which then does not seem to want to slide out. My thought was to just use the online activation tool without swapping the SIM if I need to go back to the Bionic for a period of time. If anyone has a similar experience with using this method for swapping phones, it would be great to know.
Hey guys,
I have a new HTC E8, rooted like any respectable XDA member. I'm from India and travelling to Singapore, and there's some weirdness with my Airtel nano SIM and the SIM 2 slot. I have a local SIM with 3G in Slot 1.
For the first two days, Slot 2 would occasionally disappear, with the phone claiming there was no SIM in it. Opening and closing the tray would restore the connection. On day three, this stopped working. No amount of reinserting would get the phone to recognise the SIM.
So I swapped the SIMs and both work. Swapped them back and the Airtel doesn't work in Slot 2. The local M1 SIM has no problem in either slot, but I obviously get only 2G in Slot 2, and the whole point of a local SIM and a dual SIM phone is to get cheap data when on roaming.
Help me figure this out? Either the Airtel SIM doesn't like Slot 2 anymore (it used to work), and refuses to work on it, or the phone doesn't like the SIM, or there's simply a loose contact (but that doesn't explain why the other SIM works).
So pretty straight forward
I have the s7 singlem sim version
Can i modified the sim so that it can fit and read the sim?
Sorry, you can't. Single SIM variant doesn't have the necessary hardware to operate a second SIM (even though the software side of it supports it). You's have to get a Duos version to use the second SIM, however after reading reports of high battery drain, I'd rather stick with a single SIM.
Single SIM variation doesn't have the essential equipment to work a second SIM You's need to get a Duos variant to utilize the second SIM, however in the wake of perusing reports of high battery channel, I'd rather stay with a solitary SIM.
Okay then, case closed
I have a doubt, my phone is double Sim Card, but the company delivered it blocked with a sim slot, the sim tray has plugged the slot for the other sim. I got the tray with the two slots open and I do not read the two sim only one, is that if I download the original samsung firmware will enable the other sim?
My phone is a Samsung Galaxy J5 Prime (SM-G570M)
Are you certain you actually have the dual-SIM model of the phone? It seems more likely that they have shipped you the normal one-SIM model by accident, rather than that they have taken a dual SIM phone and stuffed a one SIM tray in it and changed the firmware to disable the second SIM.
If you in fact have a one SIM phone, return it and ask them to send the correct model. The single SIM model of the phone doesn't have the connector or circuitry there to read a second SIM.
Alright, so a little back story on the problem i'm having:
I've got a Mofi4500 SIM4 wireless modem with service from an MVNO using T-Mobile's network.
The service worked great for the last several months despite a video throttling issue. Long story short, i determined the Phone number associated with the SIM was being throttled either the MVNO or T-Mobile, so they're shipping me out a new SIM card.
Here's the issue: They disabled the current SIM (which is providing us service) when they programmed the new SIM before they shipped it out. In the MOFI's control panel, there is no phone number detected on the sim (did they delete the phone number remotely?)
So we're currently dead in the water with no internet access, and my wife isn't too happy since she works from home. I called their tech support to get the SIM reactivated, and they said no problem, should be done within an hour.
2 hours pass, still not working! I jump back in the MOFI's control panel to see whats going on, and it seems that its still not detecting a phone number on the SIM. The Sim card, SIM ID, and T-Mobiles APN are all detected and correct, but the Phone number is not. even now (the next morning) after several reboots of the modem and factory resets there is no phone number detected.
We USED to run the MOFI on AT&T's network and still have that sim card, so i popped that in the MOFI to see if it could detect a phone number on that sim, and sure enough all that information along with AT&T's APN is there. so the Mofi's sim card reader isn't broken, it does have the ability to read a sim card correctly.
My question here, how did the MVNO supposedly "reactivate" the sim card remotely when the sim card has the Phone number deleted and the router has no access to the web? is it even possible to change a SIM's phone number remotely? Is it possible to reactivate a SIM remotely when the SIM has no access to the internet?
If it is indeed possible, any idea on why the sim not able to update?
