Some time ago I posted on this forum re no end of data 3G dropouts on my Galaxy SII meaning I was experincing no end od 3G data drop outs. Well anyhow today I decided to do some experimentation and to swap SIMS.
I have two mobiles, a Galaxy SII and also a Samsung Omnia 7 WP7 Mango. I decided to swap SIMS, put the GSII SIM in the Omnia 7 and the vice versa.
I switched both phones back ON as usual, inserted the SIM PIN code and bith phones booted up without any hassles.
Now here is the interesting thing. I ran both the phones for about 40mins, thinking and assuming if the SIM was faulty from the GSII the Omnia 7 would start to play up, but unfortunately both phones ran without any hickups and better still the GSII and the Omnia 7 did not face any data 3G internet dropouts, the GSII ran well and not a single data dropout and the same went for the Omnia 7, but my main focus here was more on the GSII.
But as soon as I put the SIMS back into their original phones the trouble for the GSII started again a bit later on.
So here the big Q whats the fault here, the phone or the SIM.
My guess is that the sim that is originally in your GS2 is faulty. Perhaps the sim is worn where the sim is touching?
You ruled out a phone issue when you put another sim in your GS2 and it was running fine.
Just my opinion anyway.
Thats correct when I inserted the SIM from the Omnia 7 (my other phone) into the GSII and left it running and on the data/internet for 40mins or so I did not get one droput what so ever and the same goes for the SIM from the GSII in my Omnia 7, so i.e a sim swap.
But the funny thing is non of the data on both phones dropped out.
Now assume if the SIM is the GSII is faulty, why didnt it cut out or I loose data connection when it was in the Omnia 7, this is what I cant figure out.
Also can a faulty SIM cause this problem.
I'm assuming that the Omnia7 has better contact points on the sim from your GS2. And that's how it's not faulting.
Are you only losing DATA and still retaining all phone signal?
If that is the case then it may not be a sim issue but a carrier issue based on which baseband version you're running on your GS2?
It could be the pins of the Omnia 7 are slightly more raised than that of the GSII, probably the GSII ones a slightly more flat so the contact of the SIM and pin is just touching or skimming the surface or yet again the SIM is just faulty.
Now the other funny thing here is, say for eg if I am on the phone i.e a call and the data all of a sudden drops out, than my call will drop out as well. But this problem is more data than call.
How do find out what baseband I am using and can the carrier fix this issue.

Hi Folks,
I was having the issue with my Vario II (on my 3rd Handset) where the phone enters standby and never wakes up until a soft reset.
When the 3rd handset arrived I decided to bite the bullet and go for WM Black and see if it made the handset any better. Unfortunately, as good as the new ROM (now on V2) is, it didnt solve my hanging issue.
The next thing I decided to do was change the radio ROM. I first went to the 1.38.10 and then to 1.38.11 and then to 1.27.00, as the later was decribed as being the most stable.
As you have probably guessed by now, the issue still plagues me....Even more so since the radio upgrades. The symptoms are as follows;
- Some calls I answer go silent after around 30 secs and I need to soft reset
- The phone can show full bars of signal but the phone diverts to answering machine
- When connecting to the internet, the icons shows as connecting but then drops to no signal (showing a !) then after a while will start to reconnect. Sometimes I need to soft reset to get the connection again
I am wondering if there is something else I am missing that could be causing the issue. I am using it today with no apps and still have the same issues as above plus the freezing issue.
Is there anything else I can change???? or am I just cursed?
Any help would be much appreciated.
Cheers and thanks in advance

I would say, try your SIM card in a TOTALLY different phone (not just a different Hermes) As you would have to be fairly unlucky for it to happen with THREE seperate devices, especially with different ROMs also.
If there is a handset available to you that is either a tmobile or SIM unlocked.....give it a go.

I belive it's your SIM card also..ask your provider to replae the SIM card for you. Just tell them your issues and it happened to three handset with the same SIM. I bet they will able to replace the SIM card without charge.

Yep SIM cards cost JACK ALL to the providers. If they do charge you then thats gotta ring alarm bells!!!
Hanging on wake-up was my big disappointment when going from Vario I to Vario II.
It decreased after upgrading to WM6 (first black 1.2, now black 2.0). In my case the SPB mobile shell also did not seem to do the problem any good, probably because it starts the 'now' screen on wake-up.
I have not much software on my device and have very few hanging issues.
I work for a Cingular retailer, and I just signed my fathers business up. Someone had told me that the IMEI on the account had to match the phone on a 3g phone or the exact same symptoms you are seeing would occur. I confirmed it with my pop's business. the three people using 3g phones had serious problems with calls going to VM, not getting txts, and poor service in general. Once i fixed the serial numbers Cingular-side, everything was peachy. This happens to be my first post (longtimelurker) so if I'm full of ****, feel free to tell me. Check with your service provider and make sure they have the right IMEI on file. If not, you'll prolly have to go to a store to have a clerk fix it, but it'll be worth your trip if im right .
Hope I helped.

I don't think IMEI is the issue here. I just signed up with Cingular and got a Motorola K1..but the SIM is a 3G sim. I simply pop that into my Hermes and it's been working for 2 month now without any issues. Another thing with Cingular...the IMEI on their database is automatically updated..it's not like you have a Motorola phone and switched the SIM to a SonyEricsson phone and still using the Motorola IMEI #....it will not work that way. In fact, all GSM providers will automatically update the IMEI in their system once the SIM is registered in their network. I can confirm that with my HTC tytn with the Cingular's online account. You can check the online account pretty much on what type of phone you current have. If I use the Motorola K1, the online account will be updated as unknow phone due to it's new I guess...but when I use the HTC tytn..it's automaticlly updated as HTC 8525...even I manually change the phone type to other phone...after couple minutes..I log back on and it will show the HTC 8525 again. Base on this, I am sure IMEI is not the issue here. One thing to note is that I did get that hanging on wake up when I have the SPB software installed.
i can concur about the IMEI... i havent changed my IMEI on my account since i had a sony ericsson a few years back... and i have no data problems.. i take that back, i had some when i first got the 8525, but then found out i needed the white 3G sim, since then it has been flawless.
Awaiting Sim
Thanks for all the advice. I tried the phone with someone elses sim card the other day and it seemed to behave itself. I am going to phone t-mobile and ask them for a replacement SIM.
Will let you know how I get on.
Cheers

AGGGHHHH!
It doesnt get any better....
I just phoned T-Mobile and asked them for a replacement SIM to be sent out. The girl I spoke to said that she could order me a new SIM which would be out in between 1-3 days but she would have to disconnect my current SIM when the new one was despatched! This means no phone for this time, which I need for business
I asked whether I could phone for activation when the new SIM arrived but this she tells me is not possible.......AGGGGHHH!
She did suggest that I could pay 15quid for an 'interactive' swap over at a T-Mobile store but I have issues getting to a store during the week and they are then going to see that VM6 Black edition is on the phone!
Any suggestions?

What the hell?!?! Thats bullcrap if ive ever heard it, when i got a replacment USIM from O2 my existing one worked until i called O2 to activate the new one? Maybe T-Mobile has a backwards way of provisioning them?! That sucks dude. Suggest you call them again (if you havent already got an order through) and do another request...you may hit the jackpot with a different operator?!

As far as I understand how GSM works...The T-Mobile lady is correct. You can't have the two SIMs having the same #, one has to be deactivated before the new one is active. But if you are sure the new SIM will get to you in a day or two, you can have them to schedule deactivation of the old SIM two days later, schedule the new SIM to be active in two days..the only donw time you have is probably a an hour or two if the timing is correct. If you are able to go to a T-mobile store for direct swap, you can get the new SIM working within an hour but they shouldn't be charging you $15 at the store even you have WM6 black on the phone becasue the phone is not faulty, the faulty part is the SIM and they should honor their warranty.

Agreed on the warranty there dude.
O2 simply sent out a replacment USIM, obviously not activated yet. It arrived and i called them, they took the sim card number and said I should lose reception on my existing sim (it wasnt 3G ready) and thats when i should put the new one in, as soon as i lost reception i swapped and it was working (got the U symbol straight away).
I figure T-mobile would do the same?!?!
Bit the bullet yesterday and paid 15 quid for a new SIM card. It has made he haw difference. Still got major issues. The phone has no signal most of the time and even on the rare occasions when it does, the calls go to answerphone.
The signal shows an exclamation mark (!) and the only way I can get rid of it is to do a hard reset and it works for a couple of hour (or less). It is as though it is constantly in flight mode.
I noticed that the SIM cards keep changing every so often.
The new SIM cards have a smaller gold-metal surface area, whereas the older ones have a bigger gold-metal surface area.
Any ideas why?
Is there any benefit to swap out your SIM card to the newest? The SIM that comes in the box has a smaller gold-surface area.
(When was using previously using the iphone, my SIM was pretty beat up from switching phones all the time and the gold-metal part practically had indentations, which did give me reception problems. When I swapped it out with a new one at the store it did fix the problem. Obviously a surface contact problem.)

Here's the pic.
I did have a weird situation where replacing the sim actually somehow increased my data speeds...the old sim was only a year old ...but i ain't complaining
didn't really notice any less surface area tho

That's interesting....hmmm....now I'm really curious haha...
I swapped out my 1 year old SIM as well and now im getting 3G signals in my house whereas my old sim would drop 3G service more often.
Idk I change sim cards for all my phones since g1 since there's nothing on it ever since using google contacts

There is typically no need to replace your sim card unless you are having problems with it (ie not registering on the network.)
However older sim cards have a restriction on how many times they can register on the network, and after they hit the limit the phone will stop connecting, so if you want to prevent this issue (usually takes a couple years, and is a lot more likely in areas where your signal drops, for people who travel a lot, and in 3G coverages areas where you swap back and forth between 3G and 2G) you can use one of the newer sim cards. To Identify whether your sim is the newer variant with no registration restriction look at the back where the gold contacts are, if its a newer sim it will say in small lettering "TMXXXX" (where X is a number, ie TM4322) and it will also have an expiration date printed (it must be activated by this date or it becomes unusable.)
In terms of 2G/3G the sim card itself and its age should not make a difference as the capability to connect to those networks is dependent on the phone, not the sim. You can think of a sim card as a gateway that connects your phone to the billing system and authenticates it.
Having had said that, if you are having connection issues it could just be a defective sim card, to check, just place the sim in a phone that isn't having any connectivity problems, if it starts having problems, replace your sim.
In terms of the digit you highlighted in that picture, I believe it has to do with the manufacture year, although if I remember correctly its digits 4 and 5 that make up that information, but otherwise isn't anything important to a consumer.
well i got curious and checked ....i have the bigger sim ...i don't think the numbers matter much

That's what I thought...until a lot of people started noticing better 3g connection/speeds with the new sim cards. Just a placebo effect perhaps?
The size difference could also be for users who want to make it a micro sim so they can put it in their unlocked iPhones. I don't have either of these sim cards to compare, so I'm not sure.
hmm.. the sim im using is almost 8 years old. its been moved from phone to phone so many times there are wear marks on the contacts. still works fine though.
When I first got my g1 a few years ago I had issues with the market. There were apps that I knew were available (private apps) but I could not download them. I went to a T-Mobile store and looked at the display phones. One of them was able to see private apps, the other like mine, could not. I talked it over with the rep and we decided to replace the sim card. It was a random, no other ideas, decision. Started the G1 back up and Market was now working as expected. There were no other benefits noticed. Since then, I tend to replace the sim anytime a new phone is purchased.
Your milage may vary.

When I got my Vibrant, coming from the g1, tmo wanted to just pop it in the Vibrant. I made them put in the new sim card just to be safe, figured the one that came in the box brand new SHOULD be better.

Its only on the newer ones, the old ones don't expire, they just stop working after a set number of registrations on the network.
In regards to sim issues, they really shouldn't have any impact at all. Changing a sim card refreshes the billing information in the system (like what kind of services your phone is supposed to have and what not) customer care can do this without the need for a new sim.
Hoenstly though, sometimes a sim replacement is needed, I've seen stranger things.

When I bought my phone out right, the rep opened the box and took out the SIM then sold me the phone.
I guess it doesn't matter since swapping out your SIM at the T-Mobile corporate stores is free.
I just tried this since there is a tmobile store across from where I work. I used SpeedTest app and ran it 3 times before the swap. Average was about 2500 kbps download and 300 up. I swapped the sim out, went back to the spot where I originally tested and ran three more times and got about the same rate with the new sim. My old one was about 3 yo from when I had my Dash.

I'm thinking the only time one would see a difference is if they are having poor contact surface from the SIM wearing out. I've seen ooolld SIM's where the metal had indentations like no other.
Just read the thread and said why not had the same sim card since I first signed up with tmobile 5 years ago.
When I talked with the rep on the phone and explained this to him and asked could this help he stated that the official tmobile policy is if the old sim card works no need to switch. However, because of the technical specs on the card could cause better reception, they just can't guarantee it, they only guarantee it will not get worse. He asked if I was having issues and I said no i'm just a nerd and wanted to know if it would help. Just swapped it out going to give it a test around the house and will report back.
Back Story:
Upgraded from G1, perfect 3G everywhere in chicago, couldn't even get it to drop from 3G no matter where I went. With the Vibrant and and old sim card, constantly dropped to 2G no big deal still was speedy
New Sim Card:
will report after testing
Old Sim Card
My connection constantly jumped from 2G to 3G all over my house constantly
New Sim Card
Solid 3G all through the house, will report back after tomorrow when I travel all over chicago
Okay, so - first off, let me give a quick intro: I am really sorry if I post this in the wrong forum. I AM a noob.
I've been a long time reader (and a very happy user of the great knowlegde base and ROM development here on XDA!) and this is my first post. I'm not anywhere near to be a Linux/Android wizard but on the other hand I have gotten S-off and root on my Wildfire S, have tried different ROMS, link2sd, modified GPS files with root explorer etc. That's kind of my level.
-------
So - now to my question. Please be patient with me, it's hard for me to explain in simple terms and english is not my first language. I WILL get down to facts and numbers.
I've decided to move to a more powerful device and I have just bought a Galaxy S II, bought unlocked from my provider. So basicly all I should have had to do when I got my GS2 in the mail was to pop out the SIM card from my Wildfire S and pop it in the GS2 and it *SHOULD* have been working. Problem is - it works 'kinda'. Yes - it works in the worst way - from time to time. I am puzzled!
I get very bad reception and most times NO reception - no signal.
The SIM card does not get rejected by the phone as if the phone was locked, and if I go outside I CAN get a signal, and I CAN make calls. Sometimes I have been cut off. Now I'm not talking about me not just getting data or GPS signal - I'm talking about 2G GSM signal for just making calls and texting. But outside downtown I HAVE had the H+ sign for data appear and I HAVE downloaded from market with the troubled SIM card.
So one would think that the antenna/modem(?) in the SG2 does not work properly. Well - I got me a pre-paid SIM card from the best covered provider in Denmark. I pop the SIM card in - I get a fine signal. Data and GPS works well, calling and texting - no problem!
I have tried 2 other SIM cards from my provider from friends phones - CBB using the Telenor network - and results are the same. Very poor signal, sometimes no signal.
So here's the facts from inside my appartment in a larger city well covered from several providers in Denmark:
- SIM card from my provider in Wildfire S gives me a signal between -80 and -90 dBm and 10 - 15 asu. All functions work, GPS, 3G data, calls, MMS, texting.
- The same SIM card in the GS2 give me at best around -100 dBm and 5 - 6 asu but often drops to -111 dBm and 1 asu. I have seen -113 dBm. Useless.
- SIM card from another large network provider gives me 80 - 95 dBm and 8 - 15 asu.
- I have checked if the phone is locked - it is *NOT* SIM locked.
Remember - this is all in the same place in the same chair in front of the same table. If my provider had a poor signal Wildfire S should be affected as well.
Can my SIM card from my provider somehow be incompatible with the SG2? I have of course called my provider and explained all of this. They had NO clue why it happened but would mail me a new SIM card before doing repairs.
After a factory reset Wildfire S will pop up and ask me what provider I am using after detecting SIM card (select SIM service prompt). SG2 will do the same thing on the pre-paid SIM card - not on the SIM card from my provider. Does this mean anything to any of you?
Is there a way to determine the type of the SIM card in the phone? I would like to know if the two SIM cards are of different types using different technologies - whatever - so I could determine if the SG2 was not compatible with my providers SIM card.

If you are still with me this far - thank you very much!
I had a somewhat similar problem that I solved just this morning....
Here in Costa Rica there are now 3 carriers, ICE which is state owned and two private carriers, Movistar and Claro.
I bought my S2 unlocked from a fella that bought it from Claro. The chip I was using was an old GSM chip that I was using in my previous phone. I had data connectivity but it was slow and calls dropped constantly with my chip. I have another phone with a brand new chip and when I would use it all was good. The old chip also had an R on the signal for roaming most of the time, and it always thought it was roaming when I had market enabler programmed to fake at&t so I could get to certain apps.
But this morning I went to my carrier and got a new chip and all is good.
Bottom line, go to your carrier and ask for a new chip. There may be something in the programming not optiized for the phone you have or the current network
Actually, cdzo72 could be right.
Check how old are SIM cards you were using.
Prepaid one should be no older than 1 year, meaning new tech included.
Try to find someone who recently got new contract with same provider U are using (CBB) or at least new/replaced SIM from them.
Few years ago my provider forced me to change SIM card on renewing contract since SIM "is no more fully compatible with new technology in modern mobile phones", whatever that means.
Thank you for your time.
I have a new SIM card waiting for me in the snail mail tomorrow, and I hope that it will work.
My current SIM card is 3 years old, and when I got it, it was on the same occasion as Bodisson - I got a new Nokia, and my old SIM card was not compatible with the new phone.
If this is the case however, I cannot help to think about why my Wildfire S works without any problems at all with the current SIM card. One should think that the two phones use the same technologies.
Oh well - if it doesn't work with a new SIM card the GS2 is in for repairs on monday.
The worst thing is that I have had the phone for 10 days and I feel as I did when I was 8 years old and didn't get a Commodore 64 for christmas! I want to play with my new toy!
Hello everyone, i have a Galaxy S3 with cyanogenmod 10.1 installed. This morning my cellphone started to give me no signal, I initially though it might be some problem with my carrier, but clearly this is not the case. I tried to swap SIM cards with my mom cellphone (another S3 with ROM stock), and the two SIM worked. I put again the two SIMs in the respective phone, and my phone still couldn't get signal with MY SIM, while with my mother's there weren't any problem
Basically: my phone can't read MY SIM out of the blue, but my SIM works with other phones. And my phone aswell works with other SIM. This seems to me without any sense. Can someone figured out why it does this?
I tried to wipe the phone, change rom (from cyano 10.1 to 10.2), the issue is still there.
Hello all,
I am having an intermittent but a strange signal problem with my wife's OnePlus X and I suspect that this is some sort of software issue with the modem firmware and not a hardware fault.
Basically if you reboot the phone, 9 times out of 10 there will be absolutely no signal whatsoever on the 3 UK network, the phone will just state emergency calls only. This happens on both 3G and 4G, but we usually have 4G turned off as there are not many areas within our region that support 4G yet. If you search Available Networks 3 doesn't show up.
Usually leaving the phone for hours the signal will come back, but sometimes it can be fixed by going into the Test Menu by putting *#*#4636#*#* into the dialer and going to Phone Information -> Toggling the Radio off and On a few times, but this doesn’t work every time. My phone is also on the Three network, so I have tried putting both SIMS's in the OnePlus X at the same time and the same issue occurs in both SIM Slots. If I put a Vodafone SIM in as well as the Three SIM, the Vodafone SIM works absolutely fine, regardless of the SIM slot it goes in, but it maintains a signal each time. The problem isn’t signal in the area as we have full signal in our house. If I put my wife's SIM into my LG G4 it works absolutely fine 100% of the time.
Three will not help us as the phone isn’t supplied by them, this is getting to the point now where this phone is becoming unreliable to use because if you have to reboot, chances are you won't have any signal for hours on end.
This happens on OOS and CM13 and has done for months.
Has anyone come across this issue before?
Just wondered if anyone else has experienced this?

I have the same problem and solution is nowhere to be found...
Did you find any solution to this? I've got this problem with my OPX.

Hello all,
I am having an intermittent but a strange signal problem with my wife's OnePlus X and I suspect that this is some sort of software issue with the modem firmware and not a hardware fault.
Basically if you reboot the phone, 9 times out of 10 there will be absolutely no signal whatsoever on the 3 UK network, the phone will just state emergency calls only. This happens on both 3G and 4G, but we usually have 4G turned off as there are not many areas within our region that support 4G yet. If you search Available Networks 3 doesn't show up.
Usually leaving the phone for hours the signal will come back, but sometimes it can be fixed by going into the Test Menu by putting *#*#4636#*#* into the dialer and going to Phone Information -> Toggling the Radio off and On a few times, but this doesn’t work every time. My phone is also on the Three network, so I have tried putting both SIMS's in the OnePlus X at the same time and the same issue occurs in both SIM Slots.

Are you sure it's not the carrier's fault?

My wife ended up getting rid of the phone a few months ago, she couldnt put up with it any longer as it was just the same. I don't think it was a hardware fault with the phone as it worked fine on any other network but Three. The phone supported all the frequencies that Three offers, so I have no idea why it didnt work right but certainly something wasn't right.

When I had recently visited the UK, I had trouble connecting to the Three as well(through my home SIM as International Roaming). It didn't work so I ended up buying an O2 SIM that worked just fine.
I fixed it by putting some scotch tape over the back of the sim card, My OPX is almost 2 years old and the sim card is not in good contact with the phone inside I think.
