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.

Any new info on switching back and forth between LTE phones and Standard 3G phones?

Given the TBolt has the sim card, it seems it would be a little crazy to switch back and forth (if not impossible). This issue was touched a while ago, but is there an easier way yet? I guess anytime you wanted to switch back to the tBolt you needed to get a new SIM card. Is this still the case? Or can you use the website to switch back and forth between phones.
Reason I am asking is that I would like to use the iPhone during my work day since all of our machines are Apple based... and tBolt any other time. It just doesn't seem possible unless something changed?

I was also wondering how this would work. I have several phones and, until recently when I got my Tbolt, would switch between them quite often. Now with my first 4G phone, I wasn't sure that would work. From your post, it sounds like I could go online and switch from my Bolt to one of my 3g devices as I always have, but going back to the 4g Bolt might be a problem? I don't have 4g in my area, but I really am liking my bolt and don't feel the itch to switch devices yet, but I would like to be able to have the option.

Why not just call VZW and ask ?
That would be the easy way to answer your question.

They give different answers each time you call! Depends who you talk to.

if it helps, sim cards are sim cards and the one in the tb (though it works in a slightly different way than what would be normal for a sim) is the same as any other sim card. However, if you switch to activating a 3g phone without a sim card, they will deactivate your tb sim card for sure. They may even if you don't, just because they're verizon and are slightly clueless on how sim cards work still.

Can you ever switch phones online without calling Verizon. I have never been able to do it other than when setting up maybe a new phone but never switching back to an old one. Good luck though it would be nice to be able to freely switch. I have a DInc and OG Droid just sitting here

Switching from 4g to 3g phones you have to call in each time
Sent from my Transformer TF101 using XDA Premium App

I have tried switching from 3g phone to 4g phone and it is a pain. You need to call or go into the store and get a new sim card each time. The minute you place a 3g device on your 4g account the sim card is deactivated.
I switch back and forth now because i talked the store manager into giving me a few sim cards. You can also call every other day and have the customer service send you a new one. They are free but some stores will try to charge you.
Once you have the sim card all you need to do is turn off the 3g phone, place the new sim card in and it should activate itself.

Wow thats pretty sad that its this difficult.

I had tried this once and it brought up a question that I did not have the guts to answer myself. If you went back to 3g for a short while then afterwards reactivated on 4g would you loose the grandfathered unlimited data?

Just talked to a VZW rep on the phone, who I'm assuming went to talk to a supervisor or a tech, and she said as long as I keep the sim card in a place where the gold contacts don't get harmed (like in the phone), then I can keep the same sim card between activations, I just have to either call in to switch back to the TB or activate it online.. She talked to someone about this after I asked if I could have a few sent to me, so I'm assuming whomever told her this at least had some knowledge on the situation, but I guess we'll find out when it's time to switch back

Sent from my HTC ThunderBolt using XDA Premium App

the verizon rep that told you you can keep the sim card between activations is wrong. The sim card for verizon doesnt store any data its just basically a key to there 4g service. They can only be used for one activation and once they are deactivated they are dead. The only way to switch back and forth would be to have a surplus of sim cards. You would still have to call in and have them activate the new sim card before using it.
Ii have done this a few times on my thunderbolt so I know from experience.

Not sure on that having multiple SIM cards is right. I have switched between my DX and Tbolt numerous times and never gotten a new sim card. I do have to call every time when reactivating the bolt though.

I can't see how this would work since LTE and gsm cards aren't compatible. If you could do that, you could drop it in most of the decent BlackBerrys and run... But ya can't. Anyone telling you that you can isn't at all familiar with the specs.

What a pain in the butt.
Sent from my GT-P7510 using Tapatalk

just my experience...
Using the My Account web site, I can...
Change between multiple 3G phones, no problems.
Change from 4G/LTE phone to 3G phone, no problems other than... the Web site warns the LTE SIM will be disabled after 90 days of non-use, implying that you could re-use it for up to 90 days, BUT the SIM gets deactivated immediately.
If I try to change from 3G phone to 4G/LTE phone, no problems IF I have a NEW SIM card. If I try to re-use my SIM it fails and I need to call in. When I call in, its hit or miss if they can enter that same SIM back into the System (customer service can't, but tech support has done it) or make me get a new SIM.
I haven't tried switching in about 3 weeks. So I don't know if anything has changed since.
Also, I find it best to complete the equipment change before 11pm eastern, otherwise the device change could get hung up in VZW's switch/system and not complete/clear until the morning.

At this time, it is still necessry to relace the SIM card if changing from a 4G device to a 3G device. So, if you were to change devices each day, you would need a new SIM card each time. Please check out our forums for updates at our website. Go to the website for Verizon Wireless, click Contact Us, then Customer Forums. You can also sign up for email updates from this site.
Thank you and have a good day!

[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.

Able to use 3G only without physical SIM card? Network debug menu?

Is there a way to use the phone without a SIM card? I don't have LTE in my area, and I keep getting the "no SIM Error" so was thinking that the SIM was useless anyways.
On the stock ROM every time I get the SIM error, or if I remove the SIM card itself, I get no data on the phone at all. When I try to turn on Mobile Data it prompts me to insert the SIM.
On other CUSTOM or JB ROMs, I don't get the SIM error prompt but I simply get no data.
On older Sprint phones, I know you can go into the DEBUG menu to see that EVDO/3G was actually being authenticated, the handshake was negotiated, then connection type/speed/tower/hand-off status, etc. Is there such an option with Verizon phones? I'm wondering if Data is completely shut off without the SIM, or if the data connection is actually established on the network but simply blocked from being used?
PS - per recommendation I have tried using the PHONE INFO app to switch the option to NV only, but am still getting no data. Voice/Text work perfectly.

ASFAIK, the SIM does 3g and 4g. WHY? because 3g on the gs3 is ehrdp and that also requires a handshake between 3g and lte. I believe it is like using 3g tech but with the pipeline size of lte... or thats as far as I've read into it.

Thanks for the info, xicewallx. I was afraid of that, however I've read of people flashing both Sprint and Verizon variants of the SGS3 to Boost, Straight Talk (CDMA), Verizon Pre-Paid which all I assume do not use LTE/SIM. I presume this means that the SGS3 can certainly use 3G without the need of the SIM card. I'm looking for a way to default to this on the SGS3 for us poor folk who do not have the luxury of LTE yet and have to deal with the SIM error until Verizon/Samsung fixes it.
Any help would be greatly appreciated!

I was able to get to a debug screen using the IOTHiddenMenu option (through Any Cut) but it simply stated that EVDO was in "sleep state." I wasn't able to figure out how to get it to start a connection yet.

Are you in a poor signal area? Only time I've received the "No Sim" error was at my parents where the signal is crap. As for using it without the sim card, doubt that's possible since the sim is used for authentication if I'm not mistaken.

hello,
if i understand correctly, the sim card in the S3 is basically the same as all the previous world phones, meaning its just RUIM card. The MEID and IMEI are on the phone, the card it comes with is just basically a storage device in simple terms. can someone who has access to another verizon active S3 sim try putting the card into their phone and checking the IMEI that the phone reports? does swapping the cards change the IMEI in other words. I do not think it will, but interested to know for sure.
i just started playing with one of these, but i feel realy confident you can get non 4G services to work without a sim in it.

You have it just about backwords. The sim is the real identifier on vzw 4g devices. You can take a working authorized sim and use it to activate another 4g Verizon phone and it will activate under the phone number associated with the sim.

There is still an ESN /MEID that the network uses to identify the phone for the CDMA side of the network. The process is all handled by the LTE SIM on LTE phones, though.
OP: You have a broken phone. The no-SIM error is not something that goes away. Take it to a store and get a new SIM and/or order a replacement.

I'm still looking for an answer to this if anyone has any suggestions. Any way to get 3G without a SIM card?

Did you ever get a new phone from Verizon? It seems like an issue with your phone, not the network.

I have been trying something similar along the way as I have been able to get rock solid data by switching to EvDo only using the Phone Info app.
I gave determined I am connecting to a US Cellular tower when I have solid data.
But while in EvDo only I cannot send or receive calls or texts.
I am looking for a way to enable calls and text while in EvDo only mode.
Not trying to highjack just thought this is somewhat related.

New phone and new SIM from Verizon seems to have made the problem less apparent, but it still happens, especially when driving through areas where reception is a bit spotty. It's really become an issue as I rely on getting emails for business, especially while traveling, and I don't get notifications of new emails if I have no data service which I don't become aware of until I actually look at the phone. Missed a couple of important emails/meeting invites because of this already...

I flashed a VZW GS3 to Sprint. 3G data is working fine w/o a SIM card. If I put a non activated VZW card, data doesn't work obviously.
The trick in getting this to work is to use QPST to configure Profile 0 and Profile 1. When flashing to Sprint or Boost, you must also load a Sprint PRL into the device using QPST.

Turning off lte on embryo 7

My phone is unlocked and using uxma7, but I cant turn off lte when I want to save battery, I always tried to find a reliable to do this but can't. I just popped in an international sim the other day, and it let me switch back and forth, but when I put the att sim back in, I can't again, anyone can offer me some advice?

It's because att is like the crazy boss who likes to micro mange you until you start screaming. The good news is there is way, the bad news is it sticks until the next reboot.
setting-->more-->mobile networks-->Network Operators
let it search until the end of time ... eventually you'll get bunch of network names manually selected the first at&t you see on top, and it'll say registered on the network.
Now go change it around and have fun with 2G or 3G or whatever kwanzaa you like

Yeah I used to do that on aosp roms, but you can't search it on Touchwizz, thanks though
