Have (2) Sensation 4G's. Today one of them went to No Service, and nothing I do will get it out of this mode. Flipped SIM's, housings, reflashed firmware/radio, and still get nothing. It popped back into service a couple times and then went back to No Service. Now the phone is getting warmer at the bottom (between SIM and screen) so I've pulled the battery. When I go to scan for networks, it shows T-Mobile and AT&T. If I select either one I get "Your SIM does not allow a connection to this network" or something to that effect. The SIM for this phone is fine in mine. I've found a number of threads with similar reports but none of them mention a resolution.
Main question, I suspect a dead radio in the phone or other hardware defect. Is there anything else I can try to resolve this before taking it in for service?
Thanks.
You may want to give the provider a quick call to make sure the SIM card was not removed from their account by accident. I had this situation happen when I needed to switch out a burned SIM card and the CSR did not put the new SIM into the systems.
Bar that... send it in for service.
If you are using a custom ROM, did you select the T-Mo US support when you flashed it?

Luckily this is a curiousity question as the urgency worked itself out.
I have my Doubleshot connected to the Rogers network here in Canada, and I've tried other SIM cards before (i.e. T-Mobile) without issue. But this one had the representatives (and tier two support) stumped.
I walked into an Eastlink store (competing communications company although their roaming is done through Rogers frequencies) with a promotional flyer. We got talking about switching, and they offered to do a test to see if the phone is compatible. So I thought, hey, why not? So they popped an Eastlink SIM in my phone, turned it back on, picked up the network no problem. Well and good.
The problem occurs when she put my Rogers SIM back in. Boot the phone up and the network wasn't recognizing. No service. We went to Settings > Mobile Networks > Network Operators. The searching took forever then threw up and error. No networks to choose from.
The interesting part is that the Rogers APN's were present. I thought maybe the SIM card went bad. Luckily the Rogers store was across the street so we popped that into a feature phone, no issues. I then thought there was some weird (new) setting preventing it from connecting. So I booted into recovery and restored a backup from three days ago. No luck.
The problem ended up fixing itself, about an hour later, while waiting for the bus (after having given up). I made a few test calls to be sure. Since it's working now, it's merely a curiousity, but the issue stands: what would have caused this and is there any way to restore service faster? Using Tbaldens CM 10.1 if that helps.
Thanks for your thoughts.
Still very interesting. I find now that every time I reboot the phone, it takes a few minutes for service to be established. Long enough for Auto Pilot Mode (one of the apps I use in case I'm in the depths of big buildings) to be engaged. I may have to quarantine that app for a little while. Or just not reboot the phone.
My Rogers SIM is an older card. It would have been pressed in 2007 or 2008 (which is also why the fastest internet I can get on it is EDGE). It may be time I shell out the $10 for a replacement. For whatever reason, that just may fix this newly attained lag on connecting.

Just activated a new Rogers (LTE) SIM card. Booted up the phone, and service was recognized by the time I entered my login PIN. So everything looks good (as it looks like my old SIM was starting to die). I'm still stuck with EDGE, but that is due to the phone being a non-Rogers phone. No big deal there.
Is anyone else having this problem?
I've got a dual SIM SGS6 from Expansys AU (based in HK). I've got a new nano SIM card in SIM1 slot, SIM2 is empty. I've transferred my service across to the new SIM and confirmed (using an adaptor) that I can get 4G service fine on my Nexus 5.
However on my SGS6 it only shows 3G, H or H+, never 4G. I also find that every few minutes the data connection goes completely. I happened to be in the dual SIM menu at the time and noticed it went from showing only SIM1 being present to both SIM1 and SIM2 being lit up - as you can see this corresponds with the phone showing 'no signal' in the notification tray. It also keeps on sometimes showing the message "When changing SIM Card, Data service slot also can be changed. When you want to change Network mode, please go Mobile network menu and change it." (poor grammar all Samsung's!)
Has anyone seen this before or is it going to be a case of having to ship it back to them?

Aren't the dial sim versions intended for the Chinese markets? If that's the case, you may not have the correct LTE radio bands for where you live.
Doesn't seem to be that - the bands fit according to the specs and at some points it does connect properly to 4G/4G+ - it just doesn't hold it
Maybe damaged SIM??
Don't think so - it's a brand new Nano SIM direct from the network and works stably in 4G on my Nexus 5 (with a nano to micro adaptor).
Managed to get 4G/4G+ working for a while yesterday and today, but has now stopped working again.
Get a message everytime the phone boots re. network manager (as posted in OP), which doesn't seem right to me. Also finding it still drops all network connections from time to time and even switched off totally at one point today. I've gone back to the retailer requesting a return either for full refund or exchange for replacement.
What was the outcome?

Thanks for your posts Alan I am having similar issues with 1 day old Galaxy S6 dual sim in Australia with Telstra.
- Phone loses connection to carrier (both) from time to time - especially if in the sim manager screen but also just randomly
- It looks like it is seeking a network - like polling through different bands
- if i watch it for a while i can often catch it doing this
- on 4 occasions in a day this has then reboot the phone
- it has not yet dropped out during a call - not sure if this is just luck
- I am asking for it to be declared DOA but not sure how that will go yet
I was wondering if you returned or swapped your phone or found a fix.
Thanks

Sadly that sounds pretty similar to my experience I ended up returning it (although am having ongoing issues with the retailer, Expansys, in getting a full refund!) and subsequently bought a single SIM model direct from Samsung.
I have a Samsung Galaxy S3 (SCH-I535) that I was trying to resurrect as a WiFi hotspot and found that I have a couple of issues here that I never had before.
First off, I've tried putting in different SIM cards trying to activate it and the crazy phone will not read any of the SIM cards that I put in it. Before anyone asks, I did make sure that the card was installed properly. It doesn't matter if I put in a Verizon or Straight Talk SIM card. Neither one works. I always get the pop up box telling me that I need to insert a SIM card even though I have already put one in.
Second issue that I have been having recently is that anytime I take out the battery in the S3 (either to replace SIM card because it's easier to replace SIM card with the battery out of it) or to put in another battery, I lose the current date and time in the phone. Always goes back to noon on January 1st. This one is just pure irritating to me.
These issues just came up in the past few weeks and I'm tempted to just chuck the phone if I'm not able to get these issues rectified. Any help I can get on this would be greatly appreciated.

Sounds like you need to have the phone activated. Not sure about the SIM issue, but all phones get the time from the cellular network when they're powered up.

I've tried that but I still get the SIM Card message coming up even though I have inserted it. I thought that the phones get the time from somewhere and this week is the first time that I've had the issue with the phone losing the date and time once I change out the battery.

For your sim issue this setting maybe help you
Goto Setting>More settings(in wireless and network tab) >Mobile Networks>Network mode
Tap on Network mode and Select this option : Global
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?
Just wanted to share some info in case anyone else has this issue.
First P7P was highly defective. Video issues, connectivity issues, fingerprint issues, upload speed issues and a few more. Phone went back to Verizon after they sent me a replacement. I couldn't get the new phone to connect to the network, so I brought it to the local Verizon store. Guy pulls the SIM out of the old phone and places it into the new phone, and everything then seemed to work. I had assumed the new phone would connect via the eSIM, but I was totally wrong. Dummy me! Now I know
So, new phone seems to work until the first time I call a business number. Rings once and then hangs up. I can call my house and other cellphones no problem, but not certain business numbers. Can't even call *611 or #832 as both come up as "invalid number". Many, many hours of customer service at the tier 1 level doesn't fix the issue. Factory reset, clearing network connections, cache, safe mode, refreshing network and towers, nothing helps. Finally they connect me to tier 2 who thinks it may be a pSIM issue. She had me remove the SIM, and she tries to set up the phone on the eSIM. no luck, as Verizon states the IMEI number for slot 2 is not listed in Verizon's database. She puts in a ticket to get that number added, which is supposed to take a few days. She also told me that the SPAM settings (even though I'm making outgoing calls) had been problematic. She also said that some of the call filtering settings at Verizon's end can cause this, but neither seems to be my issue.
I head down to the local store and ask for a new SIM. I had asked for a new one when I got the replacement phone but the Verizon guy just put my old one into the new phone. Be advised, tier 2 says that the stores are told to never use the old SIM, and to always place a new one. Old SIMs can bring along old problems into the new phone! Well, I guess the store doesn't follow company policy.
So, getting back to the story... Today when I go in and request a new SIM, the guy says that my old SIM, which has a black stripe at the top, could be the issue as black stripe Sims supposedly have been having issues for a while now, and they've been replacing them with Sims that are totally white, with no black stripe. Why the guy 2 weeks ago put the used, black stripe, SIM back in, who knows....
This seems to have fixed the issue, as the phone numbers that I couldn't call, now work, including 611, *611, & #832.
Now, the only issue I'm having is that every time I've turned this new phone off, the color palette reverts to factory stock when the phone turns back on. My selected color palette (Settings/ Wallpaper & Style/Wallpaper Colors) still has a checkmark on it (greens in my case), and appears to be the selected, active colors, but the phone is using the factory stock blue color palette. My old phone kept the greens even after a restart, so I don't know what other issue is going on with this new phone. It's not a deal breaker, but there's something still not right.
