[Q] Did you had to replace your SIM card after using XT720 for a while?

like the topic says
did any of you had to replace your SIM card after using XT720 for a while? like after a few months or few weeks?
i know a friend of mine he had to change his SIM card after a few weeks
and now my own XT720 is constantly losing the SIM card, until i reboot the phone
if i take out the SIM card i see 2 contact spot that seems to be worn, which was previously normal.
it seems to be related to how often you use the Vibrate option
replacing a new SIM card with the network provider fixes the issue of course.
just wanted to see if other have experienced this issue
thanks

I know generally on WIND, sim cards tend to burn out for some reason. Haven't experienced it myself but I know its a frequent occurrence with some.

Yea I had the same problem. Cincinnati bell replaced my sim card for free. I originally had a regular sim card and they bumped me up to the 3g card. Which was no different but a different color. I lost service all together and it wouldn't return. Its prolly the oven Motorola hid in this thing heating the card up.

I had to replace mine within a few months, and I am also on WIND. Though, mine was an older generation (white SIM card), and they upgraded me to the 'Blackberry generation', which has the black color.

No, ive been using this sim card since 7 years lol on multiple phones and its seen countless hours of vibration. Really weird that you mention it because Im sure the carriers in my country make the ****tiest sim cards.

I've been using my XT720 on WIND with the black SIM card since Sept.2010 no failures yet.

That is funny bc I have been using my same one for about 6 years too. Now that I say that though, it will probably peter out on me. Crap....

I've been using this SIM card since 2 yrs ago and I switch it from one phone to another a lot. it's pretty worn-out by now. but still, it's working perfectly with my XT. no problems yet.

I used my sim card from an old phone when buying this and the cbw rep. put it in for me but failed to tell me it wasn't a 3g sim card. So now I have a 3g sim card and it is better. You all with old sim cards sure they are 3g cards? Just askin just in case lol.

Ya, luckily, my 2 yrs old card is HSDPA capable sim card. (Thanks to StarHub) ;D

that's a good point you guys bring up
all the SIM cards that "burned" / "worn", or whatever might have happened to them were the white ones
the black ones are fine
sorry for the false alarm guys, seems like it was a WIND specific problem with a crappy batch of white SIM cards

Yes I had to replace my sdcard. The one that came with the phone became corrupted when I was running 2.1 a while back. I bought a class 6 and it has worked better but lately I keep finding files becoming corrupted out of the blue...
*edit* sorry wrong thread I thought it said SDCARD

Sim card never been replaced since i inserted it back in Feb 2011 so 6 months
Was using an X10i and it constantly had issues with sim card, its dropped it like every 30 min.
I had to swap etc.
Alternative was to get a replacement in some weird shop. I didnt go for it.
Got an xt720 ad only looked back to sigh and x10's getting 2.3

I have not had to replace it per-say, but I have had to remove it once or twice and put it back in because the phone said my SIM card was not in the device.

Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago,

Hello, I purchased a galaxy tab 7 plus in Hong Kong. All work great until 2 days ago, I inserted another Sim card then it now says no Sim card. I tried with several other Sim cards but no luck, I did a factory reset, flashed with firmware from Sam mobile but still no luck, I don't know what else to do before I send it to Samsung for repair that gonna be expensive, help is greatly wanted, thank you.

Try to insert the sim card with the tablet on. Does it restart? If not are you sure you are inserting it with the correct side?

Hello, thanks for the answer, I tried all that already, anyway the Sim only fit in one position so you cannot take wrong.
The tab restarts when inserting card yes.
I tried also taking the battery out for 10 mins... Clean the head of the Sim compartment but no luck.

Just removed the back by pushing under the sd card slot then inserted a flat tool to unclip the lid, then removed the batery connector.
However i still have the issue, its driving me crazy as it is my working tool...

does the original SIM still work in it?
perhaps try flashing original & latest frimware updates for new/different modem.
I know one chinese version of tab plus has locked bootloaded dud to China's restrictions, I would not be surprised if they have locked down modem as well.
And for the heck of it you could always try Galaxy S Unlock app, to be certain you're unlocked.
Strongly suggest backing up /EFS folder (twice) just in case.

Thanks for the suggestion, I flashed the device twice already but there is only one file. Could you direct me to the files you are referring to please I'll take a look when I'm back home, thanks again.
Sent from my GT-I9100 using XDA

I would try EVERYTHING else before flashing a new modem. Toggle airplane mode. disable/enable packet data, etc.
First, does the original SIM still work?
If so I would give the Galaxy S Unlock a shot for the heck of it.
These other SIMs have you tried them in other devices to either make sure they work or activate them?
did you purchase device on a SIM contract??

sim issue
The original sim does work, i have put it in other phones and it works fine, i have also tried other sim but still same issue, message still say "please insert sim card"
I have purchased the tab sim free in hk so no, no contract, it did work fine since december until 2 days ago where i input a data only sim card, when i insert sim card it does reboot, meaning it detects the card in the socket but thats it.
Concerning Galaxy S Unlock my tab is not rooted i have used only legit firmware until now so im not sure about that.
PS: looking at my phone servie status it says:
Service State: Out of service

Are you sure you havent been sold a bad or expired sim card?
Id try to give samsung customer support a call at least, they will probably tell you to send it to them anyway.
Can you try exchanging this for another one where you puchased it?

Well, i bought it during my holidays in hk but i live in norway, so... bit difficult to chage it, the sim card works just fine in other devices so it should work in tab.
I tried the galaxy s unlock and during step 1 it says error for efs backup, so either because im not rooted or because my efs is corrupted.

Probably because youre not rooted.
Im wondering if the SIM could be from a small provider which isnt recognized by the device?
It should at least dected then say something like network provider unrecognized, etc.
I really dont what to say.
I would keep trying other sims, try to get a 5$ pre pay from a major carrier like O2, 3, tmobile, etc. not sure what carriers you have over there.

Well i use Telenor which is the biggest and also quite big in europe, i will call customer service tomorrow and hear what they say, but i fear its gonna rip my pockets...

did you push the simcard all the way to the bottom of the slot?
I need a pen to push it....so I wonder if you insert your sim card properly.

yes, since the first time, repair shop said they cannot help since device has been purchased in hong kong...
No solutions until today...

Solved
After dismantling the tab completely (hard work guys...) i confirm that the sim card reader is defect, the cushions that reads the card did not press completely on it so i applied a temporary fix by adding an extra layer to thicken the card so it can press correctly on the cushions. I did try this fix before with the tablet in one piece, however i could not get it to work correctly.
Anyway thanks for your help and i'm happy that i can use it again

Nexus 5 doesnt detect SIM!!! :(

Okay so I got my device (32GB,White) just one day ago , and it refuses to detect the sim. I had an airtel(india) sim which was cut into a micro sim . Are there any settings which I need to change to make it work ?
uploading the pic of the sim... Is this the proper micro sim or is it ruined ??

Have you tried any other Sims to see if that one was messed up.mine had a hard time picking up the one out if my s4

I put this SIM into another phone and its working quite well. But I havent tried any other micro sims on the Nexus yet....

Maybe any locking on some card from provider ?
Is the card coming out of a contract?

The nexus 5 is very picky on cut Sims go get a micro Sim from your provider I cut my full size T-Mobile Sim and it didn't recognize it at all I got the micro Sim from them and now it works

Also one note is the nexus 5 has different contact points for the sim inside the tray so your cut Sim won't work while another phone might as its got the same contact patterns
Sent from my Nexus 5 using Tapatalk

attached is my sim and your sim compared
as you see your bezel on the end is shorter and the contact points in the center are differently placed

are you sure its not recognizing the sim card?
try this
1.remove the sim card while the phone is on. if youl see notification that telling you that there is no sim card and restart, then its recognize the card and problem is somewhere else
2.go to settings
under wireless&networks=>More..=>MobileNetworks=>Network operators
wait until the phone will find all the operators and chose yours
if that not working go to next step
3.open SIM TOOLKIT app
Roaming Services=>Select Mode=>and try some of the Manual mods there or the Automatic
now go to step 2 and do it again
hope it will solve your problem

Yessir. I think it the manually cut sim is posing problems. I will ask my operator for a standard micro sim and see if it works. You help is much appreciated.

Hmmm, they ARE different. I'm sure the problem is with the alignment of the SIM. the contact points arent aligned at ALL .

I chose the the operator , it spent like 4-5 minutes searching.. and then came "Couldnt connect. Please try again later." I'm sure the problem is with correct contact points.
[Thanks everyone, you help is much appreciated.] I'll keep you guys posted.

I had zero success getting my cut t-mobile SIM to work in the N5. Wound up walking into t-mobile for a micro sim. Took less than a minute and was free. Had I known it was so easy, I wouldn't have wasted $8 on a stupid cutter...

I'll be getting a micro sim from my operator.... took 2 sims from them, cut them both and both failed to work..

So i just switched to an Airtel sim and my nexus 5x doesnt want to detect it.
1) I have tried other sims on my phone and they all work perfect and get detected under milliseconds after inserting.
2) Then, i tried to insert this particular airtel sim to my dad iphone and it does work and also can call from it. So yeah it is active.
3) SO! then i tried inserting my dad's Airtel sim in my Nexus and guess what ? It doesnt get detected.
Conclusion: Nexus 5x is not capable of detecting Airtel sim and so get a vodafone or any other sim card you prefer.

I have the exact same problem with my 5x. I Have an Airtel sim as well. The phone has stopped detecting sim. If I insert a new sim, the phone detects the new sim for a while but then stops detecting again. Though the sim is being detected by all other phone including a different Nexus 5x.
Not sure what is the problem here. Any help would be appreciated.
Thanks guys

T-Mobile not working with OPO

Hey everyone thanks for your help in advance... I just bought my phone and went to T-Mobile to get a new micro Sims card. After putting it in, the phone didn't recognize it. I put in the APN settings and it doesn't save it. This really sucks right now because I don't know what else to do. Any help will be greatly appreciated. And my phone isnt rooted yet, just want the stock for now. Thanks again

Is the sim activated? Sometimes on a new sim it takes a few hours to start working.
I was already on Tmo with an N5. I just moved the sim over and all was good.

What he said. If OP has another phone that uses a MicroSIM, put the sim in that phone and see if it works.
Also did u insert the sim properly into its slot?

I didn't mean the u to be directed to NaterTots but to the OP. Sorry for the confusion.

I screwed up and instead of using my old Sim card and cutting I went into T-Mobile and had them activate a new micro Sim card and put it straight in. The old one is deactivated.

The new micro Sim does work in my old gslaxy S2 phone which used an older big Sim card. Its now using a Sim adapter.

Did you insert the SIM card in the right direction and not upside down? I know thats silly to ask.

to be honest its simple man and actually nothing you needed to make a thread about. Simple go to TMobile store and try an already active sim card. Go to AT&T and see if they can put an active sim card to help you out. Basically go to anywhere that works with a TMobile or AT&T derivative and try it out. Nothing really else we can do to help you on this.
Not try to be rude or anything but its the truth. If none of that works then you may have to RMA. Also maybe find a friend or family member and try their sim . Good luck :good:

Should work. Using my one plus with Solavei (t-mobile based company) and having no issues.

First time i've also put the tray wrong. True story

Just had this problem after coming from using the phone overseas and no signal whatsoever on the phone despite numerous restarts, SIM cleaning, and chats with T mobile. After verifying the APN was correct I went to Settings-->About Phone-->Status-->SIM Status and checked to see if the SIM was connected(it showed my phone number, but was disconnected). So from here went to Settings-->Mobile Networks-->Network Operators and let the phone find carriers automatically. Mine showed T-mobile(with a little SIM icon to the right of it), Verizon, and ATT. I clicked on T-Mobile and it registered and is now working.
Probably saved me $15 at the T-Mobile store. Hope this helps even just one of you.

Moto G XT1033 Dual SIM Problem

Guys.. Does any one face this problem..
Occasionally the sim 1 goes out of network with the no sim icon.. And nothing helps airplane mode reboot etc..
The only solution is to re insert the sim every time.. It has become annoying as hell since it occurs almost every other week
>Similarly the second sim too shows disabled even when it's activated.. The reboot solves this issue..
Does anyone face this problem.. Or something is wrong with my phone.
Tap-a-talked from the MOTOG

This happens mostly when a Sim card that has been cut is used (cut from some size to microsim). If you are using such a Sim, these problems are bound to occur if it hasn't been cut properly. The best solution would be to contact your service provider and request a new micro-sim

I have a micro sim..
Also think logically.. Why would there be a problem if there is proper contact.. Lots of people use cut Sim in other mobile
The cut sim myth is a just a diversion created by Motorola to blame it on their customers.. Instead of fixing the bug..
I think it's a hardware problem.. Hence not fixed even though lots of people have faced this problem
Tap-a-talked from the MOTOG

Why do you insist this is a bug from Motorola?
First rule if you have problem: factory reset/wipe data. Problem still there? Reflash. If problem persists, try using spare SIM card/ask carrier for SIM replacement. Otherwise send in for warranty. I'm just using 1 SIM in my xt1033 cut using SIM card stapler, so far no problem.

Not only motorola every mfr require SIMs to be not cut to fit but the proper fit from the get go. Don't blame one company. I know from first hand that SIMs can go bad over time due to atmospheric conditions. After all that are pieces of simple circuitry. Most are not well made either.

I have this problem only in one of my sim cards (both are cuted), I changed the slots of both and in my case i can confirm is a fault on my sim.

Actually, the cut sim issue is not just a diversion, it is probably true. For your information, I'm also using an xt1033 of which 1 sim is cut from mini to micro whereas the other is originally a micro sim which I acquired from my carrier. I've had problems with network more than a couple of times; and guess what? All those problems were with the cut sim.

this only means that you cut them properly I also have a sim that was cut and it sometimes slides out slightly and loose contact, but it has nothing to do with the software or motorola quality...
OP: try fixing the sim in place with a tape and check if the problem persists

ooops I missed it
sim cuts should be perfect or else they will slide out.

I have been using my XT1033 with a cut sim ever since i got it a few months ago and aside from my carrier not getting much reception,i've had no issues.
