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.

has anyone used or is using a Dual Sim holder in a HTC Desire, or know of one that works/fits nicely?
I currently tuck an alternative sim between the battery and the back cover but have to take the battery out etc to exchange, would like a simpler solution.
lol same as me mate..i also keep spare 8gb card behind my case too been looking into this apparently it has to be 3g compatble ones- gonna take a punt and try one from ebay-will post a link and let you know results.
apparently some folks are using on nexus 1 so shouldnt be too difficult- also hypercard are selling some at £70(well euros) but not far off. fcuk that gonna look for cheaper alt.
Any news on this dread123 as its something i was thinking about too.
Ive never had any sucess with a dual sim, i just use a super sim in my desire so i can use three sims and dont mess around with any extra bits. Just 1 sim card thats it

check there..got the dual sim working perfect now
hpsda and full 3g speeds..no call dropping ...no problems at all.able to switch from sim toolkit app on phone.
I am using Hypercard V3 which works on 3G too. It only reboots after switching too my vodafone card. Switching from vodafone to O2 no Problem works without reboot. You get a SIM Toolkit Icon on the Home Screen for switching.

Seems i was given false information, was told super sims dont work on uk sim cards so i gave up on that option.
Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.
I've personally experienced the differences with SIM cards.
Having been with T-Mobile (since Voicestream) I've gone through tons of SIM cards throughout the years. For the heck of it every time I got a new phone I just swapped to the new SIM.*
Ok so let's talk present day. I've noticed that the SIM cards have been changing. The large gold surface area is now small etc...
* Recently (past few years) before all the smart phones started to pop up like crazy, I was using the same SIM card with several devices. I remember getting crappy data speeds at one point then I swapped out to a newer SIM and it was night and day.
Now it looks like the newest SIM's are marked with an, "activate by," date. I wonder if there are limits to how many times that SIM can connect to the network?
Anyhow, anyone with advanced knowledge about SIM's, your input would be greatly appreciated. I find it a pretty interesting topic due to my personal experience. There has to be something with the changes that do effect the data speeds for example.
Below are some pics...

I just switched sim cards one day ago. I switched to the one that came with the phone. I notice no difference at all. The old one had been in my vibrant for about 7 months. T mobile rep told me that the only difference in sims(size of gold area) is how many contacts they will hold. I do not believe that for a minute. I just sold my Nexus One and it would not recognize the sims with the smaller gold contact area. I have been told so much BS from CS and tech reps at tmobile that I rarely believe any thing they say at this point. I am getting a replacement phone which should arrive on Monday. I just hope that it is free of most of the issues that my present one has or what I have seen listed in these threads. I really really like this phone just hope either it is issue free or the issues are addressed by LG right away if not I will send back and cancel the order. This phone has potential to be THE Beast of the the Bunch!!!!
I just got a new sim card with smaller gold area for my N1 and it works fine.

I'm also using one that I got with my G1 and am pulling down almost 6mb myself. The TMo rep stated that my SIM will work just fine, and it does. But if I notice slow speeds, I should just activate the new one and put that in.
Side note, anybody know how to activate it to your account without having to go through the completely clueless IVR? Perhaps through their website?

Closest I know of is doing a chat session with a rep through their web site. I have only swapped SIMs once when I switched to the Nexus One and had the 3G connection issues (didn't have them with the G1). Went smooth and had no problems.
I work at a retail store and the newest SIMs have a matte white finish to them and have the numbers "5.0.0.1" on the bottom. I don't know if it gets you faster speeds , but generally these ones fix most customers connection problems.

I'm having super nasty reboot issues, but I also have the SIM from my T-Mobile Wing still so I'm going to go swap it tomorrow and see if it at least helps.
I just chatted with T-Mobile customer rep online and she swap for me in 5 mins. Painless process.
Been curious lately myself. To Tmobiles reps surprise when I told them. (After they said I wouldnt have 3g or 4g) I told them I am still using my simcard from 2003.. from my Nokia 3650! I use it in my G1, I have used it in my HD2 with Android and Better windows rom for HSPA (4g) just fine..
Reps didnt really believe I am using that old of a sim card. I am however. Data speed seems fine to me. Wouldnt mind being proven wrong if a new sim style has faster speed.
I will believe the new sim cards have larger space for contacts tho.
The main reason I think there are new sim cards and they are being pushed, is due to sim cloning. Older sim cards could be cloned so you could put multiple numbers on 1 sim, or just clone it to prevent swapping. Newer sim cards however, cant really be cloned. So if you want my thoughts, its not about the data, its about the security.
That's a good observations.

As far as how GSM works i know the carriers network information is on the sim card not the phone. Hence why you can swap GSM carriers on your phone at any time. The sim card carries the prl which instructs the phone what towers to use. So getting a new sim card once or twice a year would seem like a good idea.
This is my guessamation lol

Older SIM cards, unlike the newer ones, have an activation limit (usually ~90,000 or so). Once this limit is reached, the SIM card will not connect to the network anymore. The 'activation' event occurs each time your modem connects to a new cell radio on the towers. This wasn't a large issue with GSM/EDGE because they had a larger cell radius and your phone would use data less. With HSPA(+), your phone can make hundreds of connections in a day, sometimes thousands.

Never seen or heard this one before. I mean using it since 2003 to now. I would be sure over my time and travel I wouldve connected that much and more.
First off - there is supposedly a problem for Wifi calling and the G2X and the TM9177 sim card,
many seem to find that switching to an older TM9073 (or TM9035) SIM card fixes the wifi calling problem.
see: http://support.t-mobile.com/thread/10103?tstart=0
see: http://support.t-mobile.com/message/68263
I had the older TM9073 which worked great for 2g/3g/HSPA+/wifi calling- but it died on me while traveling for work, and I was fortunately able to stop by a T-mobile store, and they gave me a new SIM --- the TM9177 --- which works fine for 2g/3g/HSPA+... but wifi calling is a mixed bag, it works on some ROMS, but not otthers.. whereas before the TM9073 works for all ROMs.

Hi all,
I have my primary phone which is an international SGSII and I have my Infuse as my secondary phone.
I experienced random reboots on my SGSII which I couldnt seem to explain and I started using my Infuse for a while now and it has now started to randomly reboot which it only has started doing since I put my sim card in it and had NEVER done it with no sim card in it so... Can these issues be being caused by a bad sim card?
The card itself is a bit old...
Please advise...
Anything's possible i guess, if you didn't change anything else or install any software on both that might have caused i would assume it would be the sim card.
Try one or the other for a day without the sim card and the other with sim card and see what happens. Then switch and re-test.
Interested in knowing if it's the sim card or not, as a last resort you could just buy a new sim card from an AT&T store.

Very possible since Samsung has implemented (since the Galaxy Tab 7" i think) a little "feature" where it forces your phone to reboot when it cant see the SIM. Its possible that the SIM is loosing contact and forcing a reboot. Hard to be sure though.
Wondering if anyone can help, im using team Eos European 3g rom zoom. now i tried 1 sim card and the 3g works perfectly but when i try my other sim, i enter the pin code on screen , it accepts it, then immediately says "Sim card removed, the mobile network will be unavailable until you restart...." .
The sim card definitely isnt broken because it works in my phone and 3g modem on my pc. I've tried restarting the xoom with Wifi off and no luck.
Thanks

how old is that "other" sim card? Reason I'm asking is that sim cards use different voltages and old cards tend to cause problems in modern devices.
Around here, providers usually swap sims for free if you say that you've got a problem with one, so I'd go for an exchange if your sim is older that maybe two years...

Its actually brand new, got it on the weekend. It works perfectly everywhere else. I think i'll go to the provider anyway today and see if i can try a sim swap.
This really is baffling me now. I went back to the providers store and tried a different one of their sim cards and it doesnt work either. I just cant understand why my xoom can read certain providers sim cards and not others? (Its definitely not network locked). Could it possibly be the type of sim card (as in a 32k vs 64k etc)?
Any help would be greatly appreciated
