Sprint note 3 sim card has locked. - Android Q&A, Help & Troubleshooting

How can I stop a rooted sprint note 3 from locking the sim. Im using this with an unlimited data sim card as just a tablet. It will work for 10 min at a time before it says sim card locked. A reboot brings it back. I know it's not a network issue as it will do it if I start the phone with airplane mode on and it locks right at the 10 min mark.

Anyway to test if Galaxy Note is truly unlocked?

hey everyone, i'm about to buy AT&T Galaxy Note through Craigslist.
seller states that it is unlocked, but not rooted. is there anyway for me to verify it is unlocked?
is it simply inserting my T-Mobile SIM card and making sure it doesn't say phone is locked, enter network lock control key, etc...?

Yes all you have to do is insert your sim and it will either connect, or you will get a prompt to enter the PIN. If you want to use 3G/4Gish though, you will have to root and flash the t-mo radio that's in dev section.
P.S. With most Samsung phones, you can check for the unlock by dialing *#7465625# and it will tell you directly if there's a network lock on it, but Samsung disabled this on the skyrocket IIRC and kept it disabled on the note

perfect. thanks for the quick response!
When I inserted a tmo sim into mine nothing happened except for it would show the sim phone number under the Settings app. No signal bars either. This is on a stock unlocked phone.

You might have to wait a few minutes for it to acquire the signal.. Is the sim active? Sometimes inactive Sims don't connect, but I put my old t-mo sim in & it had a signal in 20-30 seconds.
Easiest way to tell is to reboot the phone after you put a non-at$t sim in. If it's locked it will ask for network control key .

Yeah it was an active sim. Ten minutes later with no results. It wouldn't work without the APN at all and the Tmo rep didn't want to go through all of that (it was his sim).

It is that "simple"..
If you insert your non-AT&T (including it's MVNOs which are considered AT&T also), and it's LOCKED, it will ask you for the unlock code. If it doesn't, it has been unlocked permanently.
If after doing this, it does show your number under about, but you don't get a signal. This might be an indication of how well the phone gets a signal or how good/bad the signal is, on your carrier in the area you are testing in.
An after thought is to check the versions in the about and research. You may have acquired a hacker/tinkerer's phone that may have played further with the phone's settings and or flashed a different modem. It may also be indicative of why s/he is selling it, possibly faulty.. YMMV
You have to flash T-Mo compatible modem http://forum.xda-developers.com/showthread.php?t=1573568
thanks everyone. i bought a note from someone an hour after my initial post and it was unlocked.
i'm enjoying this phone/tablet/phablet/whatever u wanna call it on tmobile. still getting used to the size, but the display is beautiful.

[Q] Verizon activation process won't stop.

I am currently trying to flash a Verizon Samsung Galaxy Note 2 (i605) to PagePlus. I have rooted and unlocked using Casual. Currently running Stock Rooted (root66) but I have also tried using CleanROM VZW with the same results.
Currently I am able to make/rec calls and txts on PagePlus when the SIM card is NOT in the phone. When the sim card is out of the phone, I cannot get a data connection (1x or 3g)
Whenever I put the VZW sim card in the phone, it cycles through Verizon automatic activation mode (*22899?) repeatedly, freezing the phone from being accesible (Please wait while your phone is being activate msg) until it eventually times-out after 3 or 4 tries.
I have tried renaming /system/app/setupwizard.apk to bak, but that has not helped stop the activation.
Can anyone tell me what (or how) I need to do to get this phone flashed to get 3g and/or stop this annoying Verizon activation process?
The sim card I am using is brand new, purchased from VZW and is not tied to any account.
Any help is greatly appreciated

[Q] Sim error

I got this Nokia phone
since I got it been saying sim card error.
Now I know it was locked
I put in other sims and it never game me the option that it had detected a sim card and was gonna unlock
then I tried a friend's sim it detected I was able to put the code in and get the phone unlocked.
But since then no matter which sim i put in the phone does not detect the sim
Now I can't send the phone back as I'm out of the US I bought from ebay. I will see if I can file a complain via Paypal but don't want to do that unless I contact the person.
Can anyone let me know if they have ever encountered this and how to get it fixed?
thanks

I just got a 920 I kept getting a sim card error and,the phone was supposed to be unlocked. Now reseting phone by powering,off and on sometimes fixes it and,my,carrier shows up. But it always drops it.
My phone has the black update fyi
I read and,I changed automatic network selection to manual and selected my carrier. So far so good. With the notification bar hiding I never see if it connects lte, I only ever see 3g but at least the signal never drops...it,would drop and not reconnect once every half hour..

No service with ATT, but perfect signal with Cricket? Why??

So I have an ATT sim card and a Cricket sim card, both are activated. I was going to go with ATT prepaid and for the past 2 days my phone will randomly drop to 1 signal bar and then completely goes to "no service" for about 2 minutes straight with the ATT sim. I put in my Cricket sim and I have perfect service, with only drop in signal roughly once an hour. How is that? When both are on the ATT network. Is it an issue with the phone, the sim, something? I have my APN's set up properly as well.
If I had to guess, possible antenna issue, also I would try the ATT sim in a different phone.
