Using MDA 111 without a sim card

Could someone tell me if this is possible ,
My friend has recently acquired this phone and has found that he would
prefer to keep his smaller original mobile phone for calls and to use his MDA111 for internet/gprs access etc and as an organiser.
I did a search and found a thread which said you could do this with the XDA11,but don't know if it applies to the MDA111.
Thanks.

You can use the MDAIII for internet using wi-fi without a SIM card, but you MUST have a SIM card to use GPRS
Personally I chose the XDA2s specifically because it had ALL thing in one device. That way I don't need to carry two or more pieces of equipment with me; its all in the one bit of kit

Many thanks for the reply,
Unfortunately it's the gprs that he needs,
The only other thing would be to have two sims the same(multiple sims)
but according to the girl I was speaking to she said t-mobile don't do them
But the same girl also told me that the mda 111 wouldn't even start up without a sim in it. :roll:
Any ideas about which companies let you use multiple sims.
Many thanks.

Check out this guy on ebay for device that allows you to use 2 SIMs on your XDA2s
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=43805&item=6395920753&rd=1&ssPageName=WDVW
As per phone not starting without a SIM card, that is incorrect, when you start-up, it defaults to the phonepad, all you have to do is to click cancel and it gives you access to the PDA part of the device.
Goodluck!

T-Mobile do offer 2 SIMs with the same number (one for MDAIII, one for small phone) They can both receive incoming calls and only one at a time can call out. One of the SIMs has limited functionality. The service is called MultiSIM and you can actually more than 2 devices with the same number. I was quoted £30 set-up charge and £12.50/month for the second SIM on the same phone number.

As a variation I have an XDA IIs and I only take it out of the house when I'm on trips and want all its pda and other options. The rest of the time it's just used around the house and it bumps calls on to my old phone which now has a pay as you go card in it. This doesn't cost me much because I receive many more calls than I make. Doesn't help with GPRS though ... Cheers.

Dual SIM / Multi SIM experiences?

Hi all,
In my previous phone (Nokia 6230) i placed a DualSIM card. Basically meaning that I could place 2 SIM cards in one phone. A menu option was created in the phone that allowed you to switch between the 2 sims without switching the phone on/off. Ideal since I have a business number and private number... I ordered this through mobile.brando.com.hk Attached you can find a description of this tool.
Now I have a Qtek 9100, (SIMlock removed thanks to a brilliant tool found on this forum) but can't get this DualSIM to work. Does anyone have experiences with a similar trick. I hate carrying 2 phones with me all the time, so i would really like to find a dualsim that also work with PDA's / Pocket PC etc. etc.
Any suggestions / remarks?
Many thanks!

I haven't looked at your attachment, but I've used a cut sim, basically the sim where you cut your full size sims into two small ones, and fit those into a "mother sim", and put that in your phone. It's worked fine on my Magician for months. Got it from ebay for about £5. I wrote my own line switcher for use with my Today plugin so I can see what operator I'm on.
Don't buy a sim cloner. If you're in Europe, you're likely to have a modern sim. They can't be cloned yet, as far as I know.

Hi V,
Strange because my dualsim is the same, I have cut the golden chips out, but it won't work on the wizard.... Wonder why?
Sounds cool that you can switch using the today screen, i think everybody that knows how to write programs is brilliant... Is this program posted somewhere?
Ciao!

Hello to all! The experience that I have carried out with Simclone to
have been OK! I have a super SIM with 5 numbers and can
change number/operator through the menu of STK.
Through the plugin "dktoday" I can visualize the active operator in that moment (Vodafone, TIM, etc)!
Ciao!

Maarten78: I've never tested my cut/dual sim in anything other then a wizard. But what messages are you getting? I had to carefully "thicken" the cut sim so the contacts all made good contact, but once I'd done that it worked perfectly for months.
My plugin, (VJAudioNotes, evolved into VJEphemeris) has not been released yet. It's written for my specific setup, so I couldn't release it right now for public use. But DKToday is great!
V

Thx guys,
After your comment about thickening the dualsim it seems to work... It only pushes the back cover out a little bit, but i'll find something to solve that i think...
All that i now need is a tool to display on the Today Screen which provider I'm on... Sure i'll find something, i've tried the DKToday but that crashes my phone when i start other programs like explorer or inbox... Strange!
Thx tho, Maarten

I'm wondering about something that is perhaps the opposite of what is being discussed here, which I wonder about by seeing the name "simclone".
If one has more than one GSM phone or device, yet only one GSM phone line, one has to switch the SIM card between devices, in order to switch which phone to use.
It would certainly be convenient to have a clone of the same card, to work on more than one phone. Of course, being the same phone line, both devices would not be used simultaneously. But it would be nice to be able to switch between devices, without swapping the card in and out.
I have heard that this is possible with some European carriers, to get an extra SIM card of the same line, to use in different devices. It isn't possible to do officially anywhere here in the USA however, AFAIK.
So---I'm wondering if it is possible to do this somehow unofficially. How does this simclone program work?
What is this about cutting a SIM card in two? Would this work with US T-Mobile SIM cards?

I've seen these dualsim on sale in a few places, but they stated that they don't work with 3G networks.
Would that include T-Mobile, O2 and Orange :?:

Woah! Cutting a SIM in half? As far as my vast intellect spans, I would imagine you would end up.....with....erm.....2 useless halves of a SIM that used to work?!?! :wink:
T-Mobile in the UK offer a Multi-Sim option for business customers of 10 handsets or more - multiple SIMs for same number, voice calls routed to unit of your choice...not sure about SMS Texts though :?

How many sims can be active at a time?

I am planning on using an upgrade on another line to get this phone. But the problem is that I cannot just swap sim cards because of the micro sim. I would like to activate this micro sim card on my line. I am wondering if t-mobile customer service will have to deactivate my existing sim card in order to activate the micro one.
I would also like to know if there is any other charge from upgrading to this phone at walmart, anything added to the 200 dollars.
EDIT: Damn, i always do this, mods, move this thread to Q and A if you can, thanks.

Once you activate the micro sim card the regular sim card becomes deactivated .

Thanks, i also have one other question.
If i activate the sim card on my line, which i get using the upgrade from another line. Are they going to let me activate the micro sim, or will they tell me i am not eligible because my line does not have upgrade status yet.
Also, is it possible to swap phone numbers from two different lines?

Hmm that is a good question... what happened with me was, i bought the phone on the street... went into t mobile and asked for a micro sim card. They offered to activate it there, but I said no I'll do it later via 611.
But since you are getting an upgrade from that specific line/phone number I think they will:
What ever line you are upgrading, will be the line that all of the information will be transferred to the micro sim card, making it active.
Swapping phone numbers, I am not sure. Never done that.

When you do the purchase in store tell them not to activate it.. They should be able to work with you

Well, I've done this before and I dont know if different store operate differently but they have never given me a problem.
1. If there is no rebates involve, they simply activate the phone for line that has the upgrade and renew the contract for that line and activate the phone on ur sim.
2. If there is a rebate with the phone (as there is with the S3) they would need to activate it on the phone number for the upgrade and iirc you now have to make at least one phone call on that line. Then u can ask them to switch that phone to ur sim.
Tmobile agents are generally very knowledgeable, so just tell them what you want to do and they should know how to do it. If a store tells you otherwise, then go to another one.

You can also get a micro SIM to SIM adapter
Sent from my SGH-T999 using xda app-developers app

Do what I did...activate the sim card through 'my account' online, take your old sim card and punch a hole thru it using a sim cutter, then you can swap back and forth easy peasy

The phone has to be used on the line that has the upgrade.. at least a little..
Also.. are you asking about switching the phone numbers on the account because of the required data plan? Because your answer is no. You cannot use the upgrade on the other line, get the required data plan on that line, and then have them swap the phone numbers so your phone number is now on the one with the required data. ( it sounded like that was what you were asking )

Just wondering -- can a lost ATT SGS3 be used normally with SIM?

I'm a new to ATT and was wondering if a lost phone can still be used inside/outside the US when inserted with a SIM card? Or is there something that blocks the phone?

You sound like the guy who "purchased" a GS3 on Craigslist which was sim locked by AT&T when it was reported stolen. Honestly, why would it matter if you're new to AT&T? If your phone is lost or stolen then report it and they'll in turn shut down that SIM. You can report it to Samsung as well who may track stolen devices no matter the SIM entered.
Won't give any other answer as I'm sure it's a violation of the rules to aid criminal like behavior.

Haha. if i had "purchased" such a phone why would i ask? couldnt i just see for myself..?
Why would it matter? cause i just switched from VW, which as you know doesnt use SIMS.. I also just came back from a trip overseas where everyone just switched their SIM cards on the plane.. so being a new ATT customer i was wondering how that thing works.. if phones can be locked despite putting a different SIM locally/internationally.. it's just good honest curiosity. ATT CS did tell me i can put any ineternational local SIM and it'll work as long as its a partner..

You kinda sat yourself up for those kind of comments. You didn't ask in the OP if a phone could be used in/out of country.... U clearly said "lost". This is they word that will probably lead everyone that reads this post to think that 1:its a stolen phone or 2:what the guy above me said. Just making an observation.... If this is not the case maybe you should edit your OP to read differently.

Again.. this is just curiosity.. i don't understand why we can't talk about this.. i asking in general how SIM technology works whether it's active or deactivated.
Since you guys like scenarios VS hypotheticals here's one -- Imagin i lost my phone and bought a new phone under the warranty.. then later found my old phone.. will it still work if i put my SIM in? will i need to report that i found my phone? Those are valid questions that should get valid answers...

SIM cards will work in any phone. You not have to call AT&T to have them activate it. Although I don't know if the new lte SIM cards work in older 3g phones I'd assume they should. And you'd have to return one of the phones because AT&T will block the imei of the one reported lost or stolen. So you generally return the lost/stolen phone.
Edit: Also we should stop treating everyone like criminals because you find the post "suspicious".

Once reported lost or stolen...at&t will block that imei. So no, if you find that lost phone later...it won't work on at&t. Get it sim unlocked and sell it.

here is a set of answers that should help your curiosity, since you are new to GSM/WCDMA-based networks (aka most networks that aren't VZW or sprint):
1. SIM cards can be switched in phones very easily. AT&T's 4G LTE SIMs can still be inserted into previous non-LTE phones (i.e. an old Moto Atrix) and it will work fine as long as the SIM card is valid. Your phone account/line is tied to your SIM card, NOT your phone. this is useful for those who have 'beater' phones for clubbing/debauchery nights.
2. phones from providers such as AT&T are usually SIM-locked, meaning you can only use an AT&T SIM in them. You can use other AT&T SIMs (say, from another account/line) and it will still work fine.
2.a. If your phone is reported stolen to AT&T, they will blacklist the IMEI and it CANNOT be used on AT&T's network anymore, period. So if your phone is stolen, you can have it barred from AT&T. This is why people who buy phones off craigslist often run into issues - the phone is actually stolen. There are no workarounds.
2.b. If you need to use your phone with a different provider's SIM (i.e. another country carrier, or t-mobile) then you need to get it unlocked. this requires a code that you input when you insert a foreign SIM. you can buy this code or get it from AT&T for free, pending a few requirements.
3. Verizon, now that they have an LTE network, uses SIM cards as well now.

Per the insurance rules if you do find the "lost" phone you are supposed to send it to them. I know they black list stolen phones, but from my experience they do not black list lost phones.

I just upgraded an Atrix 2 to an Atrix HD; and after 3 weeks the Atrix HD for a GSIII (fix your software MOTO!). Well between those two phones they switched the SIM card form factor. The Atrix 2 had the ones they've been running since ATT bought Cingular; and the Atrix HD used this one about 2/3 the size called a micro Sim card.
My question is this; can I use my micro SIM in my Inspire 4g I have for a backup?

yes you can. if your slot is snug enough and not a push-slot you don't even need an adapter, just put it in so that the contacts are correctly aligned and it will be fine. did this all through europe when my SGS3 batt died.

I've wondered the same thing. Coming from sprint, I had to verify the ESN wasn't bad if buying used. This one done by calling sprint. I assume its the exact same thing but calling ATT with the imei number to see if its clean?

Oh, that's too bad, it's $0.37. I would see paying $0.35 but $0.37 is completely unreasonable!!!

New SIM card not detected

I lost my P3XL on a accident and recently, after 8 weeks, I got it back when someone found it laying in a Bush near the place where the accident happened - it's summer time fortunately and except a little dirt the device is fine, everything is working and no water damage!
The person who found it saw the emergency information and brought it to my address, big luck!!! 8 weeks outside, 3 times heavy rain, the fabric case it had was moulding but the device itself is just fine, crazy!
When the device was lost I locked the Sim inside the device via the provider's homepage, so I got a replacement SIM a little while later... The usual stuff what people do in situations like this
Now the problem I have is the new Sim, the provider told me that it's a new generation of Sim and the module on the Sim looks different, it's silver and the module (chip on the Sim card) has a different setup, the lines are very different! According to the provider (O2 germany) the Sim uses less electricity than the previous generation and unfortunately it's not detected by my device at all, no reaction, nothing, like there's no Sim inside...
- I reseted the network settings
- factory reseted
- upgrade to Android R
Nothing helped, however the Sim is detected immediately by my 3 other Android devices and the Pixel detects all 4 Sim cards I tried, it's only the one Sim I have a contract with that makes issues. The provider sent a new replacement Sim which looks exactly like the previous one and is also not detected.
I don't think it's in relation to the weeks it was laying outside as it's only this specific Sim card, again, the card works in all others device and the Pixel 3 XL detects all other Sim cards I tried...
I luckily found a provider that offers eSim so I could register at least the virtual Sim to make calls and have data (I wanted something that is prepaid and where I can leave every month and is not to expensive, it's 'simquadrat' now)...
It's like the hardware is not capable to detect certain Sim cards with a specific module (chip on the Sim).
Any ideas, someone else with this specific issue?

Interesting problem. Do you think the provider has blacklisted your device on their network due to the supposed loss of the phone? The sim needs to detect the IMEI and perhaps that's become the issue?
