Hi,
Just asking if GPS is working without SIM card because I recently buy one and the seller remove the SIM; without SIM I tried to use Application>navigation and nothing hapened. The phone still searching for location indefinitly....I google it and can't figure out what's up. Some says only some application will work, other says it can't work without SIM. Please, help me here.

It certannly worked for weeks in my Lg Optimus G pro phone , when i had not placed any sim card into the phone at all. It was one thing i was hoping would work completly without "web" also , so far it seems to do that fine also . Agps is not a requirement for the GPS, in this phone as far as i can tell, although AGPS can be got over the WiFi if needed, like the app GpsStatus would do that, and other apps out there.
With that said, it should be noted that in my system, the phone connects to the tower AnyFreakingWays. as the US model of phones is capable of making a 911 call (or even butt dialing one without any sim card in place.
So much of my GPS testing also included working with the Airplane mode on, and the tower fully disconnected. And it still worked. Indoors not as well, but at least it works indoors eventually, some other crappy gpses (i used) would not ever fix indooors.
In the "location" settings, I just turn off the Web locator stuff, and leave on only the real GPS, I really do not know much about how the other location methods works on the phone, because I keep turning that off.
Thank you.

Is there a "Smart Protect" or similar available for the GalaxyS?. I do have the sim swap security enabled but would like to track the phone if it's lost or stolen. I have SP on my Omnia and it's been brilliant.
i use 'lookout mobile security' there is a free version and a paid version (or 30day free trial) and i think its awesome..... i can quickly go to the website mylookout.com if my phone is lost or stolen. i can switch gps on,,, track it down ,,, do a complete wipe of the phone,,, block the phone and loads more.. all from my pc..
and it doesnt drain my battery either (i keep mine active 24/7) cause i never know when im gunna get jumped by a load of chavs when im walking my doggie lol
Thanks ADazzle I installed lookout and it works well but...............
GPS needs to be turned on all the time (cell locate too inaccurate). GPS uses google maps so consumes data all day ? GPS consumes battery all day? or am I missing something
well i never have gps activated on my phone. but when i activated it thru mylookout.com it turned gps on and tracked it down quite well... there are a few 'gps fixes' out there that could improve the accuracy.... just put it in the search bar...
ive never looked this up as im happy with my gps accuracy
OK, thanks, maybe I was confusing GPS enabled with turned on.........you are correct......from Lookout FAQ
"Yes! Lookout makes use of the Android phone’s GPS receiver as efficiently as possible. When a locate is requested for an Android device, Lookout can remotely turn on the GPS while the locate is running and then turn it back off again (locates can run for a few minutes to get the best location results). This helps to conserve your phone’s battery life. Lookout only uses the GPS to get your location when you explicitly request it.
It should also be noted that if your GPS is enabled, that only means apps have the ability to use it. It does not mean it is being used continuously or that your location is constantly being tracked"
Where in the world are you? For some countries the built in security does just this plus remote lock/wipe.
Tehpriest, I'm in South Africa. I think I misunderstood 'Remote Tracker' as being activated only by a sim swap. Probably because of the way the description is written. Having read carefully once again as a result of your post, it appears it's a full function tracker.
I'll follow up and test it. 'Lookout' is working well and has back-up and a virus scanner too.
Tried it and web responds......."for legal reasons this service is not in service in some countries"
Checked with service provider and they confirm RT not enabled in RSA
I use Prey, it works by sim swap or activation text, never had reason to use it yet, but you can use it for multiple devices so have it on my iMac and my kids phone as well.
The following scenario has happened exactly four times by now:
I use two SIM cards, one in Estonia and another in Finland. I visit Finland every weekend or every other weekend, depending on scheduling. When I visit Finland then I use pre-paid SIM card that I load with credit in order to use unlimited mobile internet the same way I use at home.
When I visit Finland I swap by Estonian SIM card to Finnish one and when I return I swap it back.
Problem is that exactly after six SIM card swaps, Google Cloud to Device Messaging service stops working and Galaxy Nexus blue connection bars stay permanently gray. This means that push notifications will not work and gTalk cannot connect at all. Other Google services - including Market/Play - work well if they can function without C2DM.
After such an event I have to restore my device to factory settings each and every time. After I do this, the device starts working again. So far I have not found a way to get C2DMA working without having to factory reset my device. The device has no developer or other rogue apps installed that might affect this in any way.
Clearing data of Android Messaging Service and other background Android services has not helped. Rebooting has not helped. Changing from data to WiFi, or to Airplane mode and back, has not worked.
My best guess is that this is some security or whatnot validation in Android code. Before Android 4.0, whenever you changed your SIM card (which I did just as frequently on my HTC Desire), it asked for your Google Account password, after which C2DM worked.
But ever since Android 4.0, your password is not asked and the C2DM stops working after exactly six SIM swaps. I know that it is exactly after SIM swaps by checking my schedule and gTalk chat logs, where I have made notes of this.
I have reported this bug and looked for a solution for this before, but have not gotten an answer. Has anyone run into such an issue or knows what I could try to restore C2DM connection without having to reset my device again? I know that the problem is very custom and thus most users never face this issue, since swapping SIM cards this often is rare.
Wow, this is insane. I actually worked it out! I had reset my phone THREE TIMES in the past handful months because of this!
Apparently what happens that there's a bug in Android that switches SIM card setting after multiple SIM card swaps. Android stores SIM card related settings internally somewhere, but apparently has a bug in restoring those settings after certain amount of SIM swaps.
I went to Mobile Networks menu and from there to Access Point Names and for some reason Android had switched to WAP service instead of the mobile internet one. This is a setting I had never changed and it's happened four times by now.
If you run into the same problem or your C2DM suddenly appears, then you should look at those settings first and foremost.
Hey guys,
I am having issues with my Xiaomi Mi 10 LTE, where i have been using my hotspot due to the company wifi being down for a whole week and having a lot of issues. Currently i am only able to use my hotspot if i use no security, as with the WPA-2 security it fails to connect to internet or just outright fails to initialise the connection. If i do connect with no security, it fails if i disconnect or if i lock my tablet for a short time and refuses to connect again. I have found a workaround where i can add security and a password, then leave it to initialize the connection... i can't connect to it even with the correct password, but if i change the hotspot to have no security again it will connect fine. I have tried resetting my connection settings and this fixes it for an hour or so and then stops working. I have tried changing from 2.4g to 5g and back, this doesn't work. If i change the sim card slot it works for an hour and then breaks again. I can use the fix of adding a password and removing it but it is generally a massive pain in the a**.
Does anyone have anything they have tried that works as a perminent fix?
Thanks in advance!
Just to add, i am connecting to the hotspot with my Samsung Tab S7+ which has had no isses with other wifi connections and worked on my S7 Phone so i am sure it is the new phone. I have had it a few months but never used the hotspot until now.
I've been having quite a similar issue, and this is the second time I get it on the same model! I guess this is a bug or an hardware problem related to the model. The only thing I noticed working, and it's not a security issue in my opinion, is the position where you keep it! try to holding it in your hand at different inclination , until you find the right position. the one I'm using right now works better when lying on a table, the previous one worked better in a standing, lightly tilted position, as you can see in th eimage
That is insane! I'll have to try a few things and I'll get back with results. Normally my phone is lying down on a table but I'll check a few positions. I have found that screen mirroring seems to have the same effect... as in it doesn't really work. I don't know if it is just data out when the issue arises as I don't have any problems downloading or streaming etc.

Thanks! another user told me he had this kind of problem but it disappeared after a couple of opdates
After a whole buncha roms, I have my mystery HTC ONE M9 working, more or less with [Sprint_HTC_One_M9_4.27.651.4_RUU]
IMEI is showing up, as is LTE IMSI and CDMA IMSI, so -- I THINK -- the phone part is finally working (can't test until I wangle a replacement nano-sim
off my carrier, cheapo sim cutters are crap). However.. STILL NO GPS. When I use a simple GPS TEST app, eventually the "sky map" fills up, satellite dots eventually update and change number IN VIEW and position, but never a fix. The only way I get any location is when I turn on "Location=>High Accuracy, which just uses stored google and wifi info.
Somewhere deep in the filesystem is something that handles GPS and it is pooched and has stayed pooched since I had the brilliant idea to install Lineage OS on a Sprint CDMA/LTE phone (had no idea at the time) (It looked and ran nice.. just no IMEI or GPS).
So, I have read all various easy fixes for GPS problems with the M9 and tried all the usual, plus the ad-filled apps but this has remained DEAD even when I started fresh from an 3.41.651.41_RUU. I have wiped everything that TWRP let me wipe. I have factory rest endlessly.
Gotta get TWRP back on it, then Magisk and get rid of the evil self-register thing..thing...thing.
This was a $60 Aliexpress refurb, which means new back case (no sno/ID) and battery and I was more or less satisfied with it until I set out on search for something more than Marshmallow/ Android 6.
Anyone a GPS expert? From the forums, I see that this is a problem for a lot of folks.
Thanks and regards, /Z
Hi everyone, just a little curious on what side of the old "metaphorical" coin my phone has fallen on. The problem this coin is concerning, is simply one related to my SIM. My phone has no cell service right now since it doesn't want to acknowledge or use the sim card it has in it. It's a 512Gb unlocked phone I special ordered upon first release, no other problems (other than the screens scratching easily) but now it's no longer working on anything other than wifi. It's the wifi that I think caused this problem actually. I just set up a new lightweight Asus RT-AX56U router to utilize two WAN ports (one built in and the other setup through a USB ethernet adapter). The problem came about after I switched down to a WPA3/WPA2 setup from a full WPA3 simply due to a connection problem one of my laptops was having (it's wifi card was one from prior to WPA3). Shortly after I did that my Z Fold 3 started having frequent wifi drop problems. After about an hour of that the connection seemed stable, then the next thing I know the phone dropped connection to both Wifi and cell network! Then after I restarted the router, only wifi would reconnect and my cell network connection has been M.I.A. ever since despite what I do (tried airplane mode, tried cache whipping it, restarting it, and finally even a full factory wipe/restart). My phone is up to date on all of it's updates (finally decided to last month after seeing that my model has no root + camera options) but nothing other than a routen cache cleaning ever happened to it prior. Just trying to figure out what my next move now should be, get a new SIM card, or is a whole new phone needed?
I would first try another sim card to see it's related to the physical card or a carrier issue. Maybe try and borrow one from another network as well.
If that fails, try a factory reset.
If that fails, it's time to reach out to Samsung.
I tried a different SIM from a different phone from the same provider (on the same contract bill). But it wouldn't register, I even factory reset it prior to trying the other SIM. So I went and got a new one from the carrier, and problem solved! (First SIM card I've ever burned out without truly trying to)
