Which SIM card is best and why? Yes there is a difference.

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...

the reps at a store just told me to makr sure I used the new sim card they gave me because only their new ones allow for the 4g network
they have a diff design hatched in the gold
but u r correct in noticing the difference

That's odd, I'm still using my sim from my old G1 and I hit 9018kbits when I did a speed test a couple of days ago.

Interesting as figured. Thanks for your input.

well in their defense , they said new sim card in respect to at some point in time they changed how thw sim cards were made and was concern if i had an old one seeing as I've been with then for years...
but
ugh I wish I got speeds like that northern cali speeds suck ...
in sacramento I get maybe 1mb if I'm lucky usually around 0.85mb/s

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.

I am in Northern Ca too, and I am getting between 2.5-4M down, and 1.1-3 Up

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.

Sim card not detected

Lately out of the blue when I pull my phone out my pocket I see a pop up saying sim card not detected then I have 2 options. Shutdown or reboot. Is this the phone quality built a little out of place or what? I'm sure someone here has seen this message if not all of ya have.

Personally I would go to ATT and see if you can get a new sim...because apparently something is not right with the sim card.
or or or
It could be the ROM you are running, If you are running a Rom...

Running android revolution 5.1.6. Crazy how could it be the rom?
Sent from my Inspire 4G using XDA Premium App

Possibly just a bad installation...
Although it is a reliable ROM they all have glitches, possibly it is the ROM and you should try re flashing it and if the problem is fixed you know it was the ROM, and if it doesnt work Like i said before, your going to have to take a trip to ATT.
It could also be some type of hardware failure in your phone, not sure though.

Have you tried using the SIM in a different phone?
Faulty SIMs aren't unheard of.

Nope just this one. It only pops up every now and then but today it did it twice back to back so now I was like wtf. And decided to ask if anybody else seen this before.

My sister once had a bad 3G SIM card that would only work on EDGE. We were right by an EDGE/3G border, so we could take 3 steps forward and have a working phone in the EDGE zone, or 3 steps back into 3G and have nothing.
My Tilt phone worked fine in both "zones," so I put in her SIM and had no signal in the 3G area, heh.

Oh.. well if the problem is persistant ill just get then to make me another similar

Uh oh...
Same problem for me here as well. Running CM7, was working fine until later in the evening when suddenly the network "died", and after several reboots noticed the little SIM problem icon next to the signal meter. I had the card locked, but went into settings and unlocked it. Now, logically if the phone couldn't read the card then technically I shouldn't have been able to change the PIN, so...
Confused over here. Is there a known fix to this? Or worse - how do I broach the subject with ATT if I have to go in?

I don't know about the fix about it, but concerning talking with AT&T, I'd recommend calling Warranty exchange first. They'll let you go through some hoops like getting your imei and possibly cleaning out your sim card with a rubber eraser. They'll also run some network tests on your phone to see if there are any "down towers" in your area. In the end, just request for a replacement sim card from them and have them note on your account that you want to get it free. Ask for confirmation if it's in your account, then head for the nearest AT&T corporate store. They'll tell you you'll have to pay $25 to get a replacement sim card or something, but just say that warranty sent you and it's noted on the account: should get you your sim for free, if possible.

I have never had a problem getting a new sim card for free from a corporate store. Just go in and ask for one.

[Q] 3G does not work 4G fine

Today as soon as I left a 4G area my 3G does not work. I tried everything and I get no internet connection with 3G or 1X. When I go back into a 4G area it works fine. But if I move back into a 3G area I get no internet connection. Do you think my CDMA modem is fried?

Im having a problem with mine in general where as my thunderbolt was fine. Either I have nothing, 3g and most of the time no 4g. Headed to verizon after lunch.

It's most likely your SIM card. Had the same issue and ended up with a replacement phone for no reason. Go get a new SIM from VZ and try it.

This solution may work but definitely couldn't hurt to try. I had the same problem you seem to be having, and flashed all roms and versions of software and still only 4G would work. I thought the 3G was fried and seen very few alternatives online besides new SIM or new phone. Saddened I went to bed with battery out and SIM out and as soon as I popped them in the next morning, 3G was normal and has been normal for weeks now. I can't explain it but it more than likely has something to do with the SIM card like everyone else is saying.

Dont know why but after a few days it actually started working. Thanks to all who tried to help.

Im in a 3g only area right now. Never really had the no data problem, but suddenly I am and my phone freaks out and I sometimes lose signal for 20 mins. I'm pretty sure someone from verizon said told me not to take out the sim card

I had sim card replaced and its still screwed getting replacement sent. They also had me do all kinds of other whack stuff that didnt work.

I lost 3g/internet also and tech support was going to send me another phone, but I tried the new sim card and Bingo. It worked! Thanks for the post, it saved me from having to flash my phone back to stock"for the warranty."

I did all the things they said to do, sim card,format sd card several times and new gmail account. Got replacement phone in and everything is working great so far.

Sim Card Testing

I've been doing a lot of testing with different sim cards the last few days, and thought I'd share my results. I have identified with 100% certainty the reason why some people on miui can't get wifi calling working, while others can. It is 100% caused by the sim card. If you have the older style sim card, with the black numbering on the front, it will work every time. Newer style it doesn't, or maybe once per 50 reboots. (That one has gold lettering on the front.)
Another thing I've discovered, (which ironically I wasn't testing for ), is this also seems to be the cause of the "apn issue" that people have on cm7. Same deal, older style sim cards don't seem to have it at all. Newer ones do. I have access to 3 different sim cards from tmobile, all activiated on different numbers. I have two of the newer style ones, and one older. Each test was done with 30 reboots each. (I was going cross-eyed by the end of it.)
1st card, new style, one I got with the phone.
- Miui - No wifi calling at all
- cm7 - Apn issue 4 out of 30 reboots
2nd card, also new style, from a different phone.
- Miui - Again, no wifi calling working on any boot
- cm7 - Apn issue 6 out of 30 reboots
3rd card, old style sim card (and although they say new ones increase the 4g speed, after multiple tests I didn't see one difference between any of them speed wise)
- Miui - Wifi calling working perfectly on every boot
- cm7 - not one apn issue out of 30 boots.
So, while this is a small sample size, (I don't have more sim cards, and I really couldn't do more than 90 reboots without loosing my mind), it seems to show the cause of the problem.
There really isn't much I can see them being able to fix this. I'm guessing the miui devs and cm7 devs are using testers that have the old style sim card, or have the old style themselves (depending on if they have the phone or not.) Now since you can't really troubleshoot an issue you can't re-create, this might be something we all have to live with.
I just figured I'd post this so people who had these issues know now they're not insane, and they're not doing anything wrong, it's a compatibility issue.
If anyone else does find something different than what my tests show, please either respond or send me a pm. I'd be very interested to see others results as well. (Like I said, correlation is not causation, so this could very well be a fluke test with such a small sample size.)

Good job on the test. Unfortunately I have a sim card with black writing, and I still have the APN issues with CM7, as well as the occasional wifi calling issue.

Damn. Well it is sim card related, but perhaps there are a few more types that I wasn't able to test with. Did you get your sim-card with the phone? Or did you have an older phone and used the same simcard in the newer one? (The old one I'm using is at least 4 years old, if that helps.)

how can i help
Thanks for the info. I bet that drove you up a wall. I have 1 maybe 2 of the old "3g" Sims. And 2 newer ones from TMobile Replacing the "3g" ones. And I have 4 brand new ones that came with both of my devices. I kept them when I returned the phone. Let me see what I can do to help. I run cm7 and modified versions of the stock rom. I have big time issues and want to help resolve this.
I agree with the comments about developers....but remember this not there day jobs and they do depend on us to submit info...but then with all of the talk about apn's you would think at least one would have fought on. I have a copy of xboarders Apn fix....never really looked at it. I just keep using apnsbu from the market. I will report back with findings. Thinks for. The post and something to do...

Oh that statement wasn't in any way meant to be a shot at any of the devs, I'm just stating that you can't blame them not being able to look at a problem they are unable to re-create. Infact, it was just the opposite. It was more like saying it's not their fault in the least.
And please let me know your results. (Yes, it was driving me nuts. I've been going through logs, the init.rc, all the added init scripts, everywhere trying to figure out why it wasn't working. This was a last ditch effort, figuring it couldn't possibly be this but there was nothing else to try. Go figure )

This is turning out to be very tedious. My old sim from my tmo shadow/Juno days is a bit unreadable. The number has been tuned and is in readable. But no worries the bb still works and disabled to read the serial number....now on hold with TMobile. I am starting to think I really called at&t. Any how what I would like to knowis how can we identify what card is what. I see some noticeable differences like the old one has a big ger gold contact area, the numbers where in black, and the design on the old one on the contact side is gray. There is. Nothing legible on it. But I do know it is one of the old ones. Is came with a 3g phone from like 3 years ago. I am supplying this info to possibly help identify what Sims work. I will post pics later if needed.....still waiting. Off topic but all three hold songs suck. If they want to keep people happy then they should get some new "caller tunes" will report back more later....25 minutes on hold now.......

I believe my sim card is around 3 years old, but I'm trying to think whether I might have gotten a new one during one of my phone upgrades. Not really sure...

Ok I can not further test this today. Turns out that they have to release the old similar card.?.?. What ever that means. Did some questioning. This is what I got. My old card is a 2g. The new cards are 3g. 3g card is needed for 4g. How to tell a 3g from 2g is a marking on the contact side of the card. 3G cards say "TM9073"
So if people could help with trend analys that would help a lot. Info need is...
1) do you have apn issues.
2) what, if any, markings do you have on the contact side of your sim.
3) what rom and version are you using.
4) kernel info.
5) baseband.
This could be helpfully to us and any developer that is willing to help figure this out.
Edit: I have not tried the miui roms. I will help as much as I can with miui, but I think this is the same issue with different Results. So I am adding in the rom question.
Edit 2) wifi calling will come up invalid sim when apn is lost on cm7

1) do you have apn issues.
Yes
2) what, if any, markings do you have on the contact side of your sim.
No markings on the contact side of the sim
3) what rom and version are you using.

5) baseband.

BY THE WAY NEW R34 128k sims are now available.
im currently running this sim and i have no issues whatsoever!

Do you know of any way on how to id this sim? From others?

If you have an old T-Mobile sim you should be able to call them and tell them you wish to change your number and service to the old sim card. You give them the number on the old sim (if you can read it) and tell them you want to do a sim swap. I have done this before on a prepaid account. I don't see how a sim could increase your data connection speed. The new sims just have larger phone books and can accept longer names, etc.

I called yesterday. They released the sim. What ever that does. So some time today I need to call back and set it up. I have many sims on hand to try but this is the oldest one. I am not worried about how many numbers I can store on. I just want to help try and find a solution to the apn issues using custom roms. Any information posted here in regards to apn or sim cards is usefull. I see people reading this so please chime in. Even the smallest bit of info could help.

Ok could not go back to old 2g sim. Rep gave me many reasons as to why it would not work after submitting it 3 time. The 3g sim I was using was new in early may replacing 2g sim. Insted of reverting back to current 3g sim I decided to use the sim that came with my g2x. I noticed that the contact area on the new 3g sim was slightly different then the old 3g from may. Both. Sims had that "T" code on the contact side. I guess it is time to test. Report more tomorrow.

Update: new 3g sim card a waste of time. Did a reboot and no data. I wish I knew where to look. Cm7 and miui seem to be a waste of time. I need wifi calling at home. Does any one have any ideas? Are their any developers willing to help? Is there some where or some one we can report this to?

Ive found the same thing as OP. WIFI started acting up when I finally switched to using the sim that can't with the phone. Never had any issues with the old one. When I pop the old sim back in wifi is perfect. I'm kicking myself now because I cant reregister my old sim because all the numbers are rubbed off.

FYI: try inserting sim in other device's. Depending on the device you can go into setting and read the sim card number. I used a @#$%berry 8220 Pearl flip. I wish you luck. I just tried to revert back to my old sim. They could not push it because it was inactive to long. Something like 30 days. Keep us posted.

Problems

So, I got a SGS2 Skyrocket a few days ago from a guy on craigslist for $400. Great deal, or so I thought. The phone worked well until today, I'm not receiving text messages or phone calls and I cannot send text messages. I first though, "great, I bought a stolen phone and and now it's been disabled." I googled it and it seems that I wouldn't be able to make calls if it had indeed been reported stolen. Any ideas? I restored the device and it didn't help. Thought it was interesting when I went to software update under settings it says "DM initialization is not ready. Check network or sim card." Could I just have a signal problem or something? I have full bars...

Did you get a new 4G LTE sim card for the phone?

No, I didn't. But it was sending texts just fine yesterday and now I'm trying to use the sim on my old phone and it wont send texts either.

Sounds like a sim issue. You might need to head to your ATT store and upgrade your sim card. This should solve your problems. Older sims won't work on the newer 4G phones. I had this issues with my 1st skyrocket and my old sim. It worked for a bit then stopped working, we replaced the old sim with a new one and all was good....

I bought mine off Craig's List and experienced the same thing. Your sim from your Captivate will only work briefly for phone/SMS, but not at all for data.
You MUST get a 4G LTE sim card for the Skyrocket and AT&T will change your data plan "type" (same data and price per month, but different line item on the billing).
5 minutes in AT&T and I was good to go.

Really? So if your information is correct, and you are all knowing, then why not help him fix the problem.

First off sounds like a SIM issue. Sim is usually the problem when it comes to network connectivity issues. Did you check the litmus sticker for water exposure?
Call ATT and have them check the IMEI #. You should have done that before you bought the phone.
@Justinfedor: That kind of response is not needed. If you can't say what's on your mind kindly please go somewhere else.

When I got my Skyrocket (moving from Captivate) the sales person said directly I would get a new SIM because the 4G LTE needed a new (assumably different) one. I'm sure you just need to get a new SIM which ATT should do no problem.

First off sounds like a SIM issue. Sim is usually the problem when it comes to network connectivity issues. Did you check the litmus sticker for water exposure?
Call ATT and have them check the IMEI #. You should have done that before you bought the phone.
@Justinfedor: That kind of response is not needed. If you can't say what's on your mind kindly please go somewhere else.

4g lte sims are for data. Like i said my friend doesnt have one in his phone. We dont live in an lte area so hes not getting a new one. U all say people need a new sim for a 4g device. Thats a complete lie. Sims can cause the issue but its not always the answer. Oh and i will go somewhere else cuz you all obvisously think you know everything. No need to be in here with a bunch of low life.

WOW! Holy childish over-reaction batman!

Can't you just get a new Sim? Worst case, is that your carrier might charge you something like $10.00......

If that's the way you're going to act, then please leave. I used to work for ATT a while back. What I don't think you get is... You're right and you're wrong. No you don't need a LTE sim. If the sim is bad it can cause connectivity issues, and weird stuff all together. That last statement is what you're completely ignoring.

Justin and X10D3 are correct. I used my sim from my Atrix in my phone since I got it. You'll need to be set up on the LTE plan through att. All that happened is their system doesn't have your account provisioned for LTE and it took a day or so for them to catch it. Login to your account and see if you're on an LTE plan. If not, then call them, but I know my sim is the same one from my Atrix and I've hit LTE areas the whole month in December with no issues. It shouldn't change your rate plan just need it provisioned for your account to register properly with their LTE network.
