I have been trying to use a dual sim adaptor with Athena but would not boot with it on. Anybody had any success? It will be great for me to be able to use both 3 and standard without removing the sim. it is a pain to remove it on Athena as this is under battery and sometimes needs a flat screwdriver to remove it...

Do you mean dual SIM or dual SD?
Dual sim of course not dual SD
Well, i've got an old DualSIM adaptor (anlog) which worked fine on my Himalaya.
My Athena boots without problems when i use this adaptor, but it takes me 3 or 4 restarts of the phone to get the DualSIM adaptor changin the SIM.
But i guess i have some issues with my SIMCards, they really look screwed up, makes me wonder why they work anyway
Maybe a newer Radio could have an impact on this Issue too.
Right now i use Radio 1.50 and AP Dual PK3.
If your SIMCards are screwed up the Athena won't boot, also my SIMAdaptor needs both SIMCards entered. With only one SIMCard in it, the Athena won't boot.
BTW: SIMDisplay (can be found on sourceforge.net) is the perfect Todayscreen Plugin for Displaying the active SIM.
I have one running but ...
finally I obtained a Simore dual sim working. But my problem is due I have one line for voice and other one for data, if should be possible to have some mechanism that in base to which sim is activated obtaining working the data connection or not. Do you know if it is possible?
Hi Beginner. Could you please post the model info of the Simore dual SIM you found worked with Athena? I'm currently looking for one. Thanks.

The Connection Setup Wizard will detect the network that you've just switched to and offer to set your data connection to match it. It'll do that every time the network changes.
If you're looking to buy a SIMore dual SIM adapter for the Athena, DON'T. The SIMore dual SIM won't let you connect to WCDMA network so you won't be able to use HSDPA or 3G!!!! I bought one from them and in the process of getting an RMA to return this piece of junk back to them now. Their online ad is fraudulent when they say it's 3G compatible. It is not. It only let you connect to GSM which only offers up to EDGE.
Is there any dual SIM adapter that will let you connect at 3G speeds out there?
PS: If you're only using EDGE at the moment and don't think you will ever never for the rest of your life upgrading to HSDPA, then by all means, flush your money down the toilet and buy this expensive piece of junk.
Thanks for the warning. Thought it was useful to have.
no dual sim
shame there is none yet. it will be great to have a truely dual phone. Networks will hate it
I think it could be posible but not easy to create a soft sim somehow. instead of having to change my three.co.uk hdspa compat sim between Athena (why the hack they do not do the sim reader as a slot accessible without removing battery) and my mac laptop is a nightmare. I tried to use Wifirouter, but it crashes athena quite often.

Under the factory ROM I never had it crash, even with hours of use at one time. I haven't used it under AP4 yet. Maybe you have a conflict with another program?
not installed anything apart tomtom 6 legal

Iam not sure what are you explaining.
are you using a dual sim system?
does it works? which is it?
thanks.
i tried using few none worked. I find very difficult in swaping sims without the add o a flat screwdriver, also removing battery is not fun.
I am wondering if it will be possible in developing a virtual sim card that will copy the info from our sim card allowing the phone to work with it?
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

Thanks for your input.
As for the exp. date, where is that located. I don't see it.

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
interesting discovery for myself a little bit ago and i cannot find anything on google relating to the rezound being capable of using either sim
i dont have pics, but i've only seen rezounds with the larger white sim
and now i'm finding out that its capable of using the micro sim (thanks swilbert80 for bringin a few more hours of my life into sim research, inadvertently of course) lol
first, i wonder if there is a performance gain using a micro sim?
seems like it is generation 2 sorta, for all i know they work just the same - but i find it very interesting that its never been discussed (or at least i cant find)
ive swapped my sim out once as advised by technical support to resolve poor 4g reception - nothing was said to or mentioned of trying a micro sim,
anyways, any and all insight appreciated, curious to know what others have as a percentage...
thank you for lookin

The only difference between a regular SIM and a MicroSIM card is the physical size different, the actual circuit and contact part of the SIM and MicroSIM card is identical.
As for resolve poor 4G reception due to SIM card? Man tech support say the darnest things. It has NOTHING to do with 4G reception. It's nothing but an excuse to keep you in the loop while they won't admit it could be either the phone or their network's problem.
Going back to the topic. I have the first generation SIM card from Verzion as it came with my good old Thunderbolt.
I've been wondering though, when the next gen iPhone which supports LTE is released, if a simple SIM swap would complete the process of activation like between 4G devices now is going to be applicable or not...

Actually sims can go bad, it's a computer chip and they can interfere with a lot of things on the phone, it's main purpose is for authenticating and utilizing the radio in the phone, so bad sim card = tons of connection issues.
I experienced it with an old AT&T sim which I used to switch between phones a lot. though micro-sim vs regualar sim is irrelevent, they are the same thing just cut different.
Just getting a new sim, either kind should fix the issue if you have a bad sim.
A simple sim swap will do the basic activation of the lte iphone when it comes out just like swapping androids.
The only exception is that iphones interface with voicemail and sometimes data differently (at least as of IOS 3.0, it may have changed.) so a call in to verizon may be required to switch the plan your on. I've dealt with this when switching between iphone, blackberry and android on my AT&T sim. That really depends on how the carrier sets up the plans

I guess they don't make SIM cards like they used to be.
My mom's SIM card, which she was given back in 1995... yes, 1995, is still kicking and works just fine even after it's being clipped for MicroSIM across 20+ phones she had in the years.
bummer, i was hoping for someone to say that the micro was gonna be the bees knees... ( yall coulda lied, i believe in placebo's)
lmao
owell, guess i'll suffer with my oversized one lol
its easy to remove and replace i guess

Lol, personally the regular Sim card are about the right size for me the micro ones I fumble around with and drop it a lot, lol.

I almost fell out of my chair when I read about the sim card doing bad reception. Even if one is going bad. Most chances are its is either going to work or it isn't. Not kinda work. A fellow Rezound owning friend and I was talking about this subject yesterday. I don't think cdma carriers have the whole sim card technology ironed out yet. I had ATT for many years and I never heard the stories of people needing to get sim cards swapped out because of something not working or because they changed phones like I have since I been with Verizon. Seems like just about every person who switches phones has to get a new sim card.
Does anyone know if it's possible to install the SIM Toolkit on AOSP-based ROMs (I'm running AOKP)? I'm living in East Africa (Tanzania) and for a couple of the cell providers it's pretty useful to be able to access the SIM card's menu. I know it's included in AT&T (or all Samsung?) ROMs but not sure if it's possible to get it working on AOSP ROMs.
Also, does anyone have a suggestion for a good dual-SIM adapter for our phone? I have 3 different SIM cards currently (much cheaper calling people on the same network, so it pays to have more than one SIM), and it would be really nice to have at least 2 of them in my S2 at the same time. Just not sure what a good one is.
Thanks!
If I end up trading one 4G phone for another, what needs to be done as far as getting sim card to work with new phone?
I was looking in to this myself. Long story short, you can swap the SIM into a new phone and it will work. Just don't activate another non-4G phone on the SIM phone # or else they get nuked. http://support.verizonwireless.com/faqs/VZAccess/4g_sim_card.html
Depends on phones. I switched from HTC Rezound to Galaxy Nexus & they use different size cards.
