Blackberry/Windows Mobile/iPhone One SIM

Here is my question. I recently received a BlackBerry from my company. I want to be able to use the BlackBerry and Windows Mobile phone interchangeably. So for example if I want to use the BB one day, I take the SIM out of the Windows Mobile and put it in the BB. If I am running the BB data plan offered by T-Mobile, will the WinMo phone data still work? I will need the BB enterprise plan as my company wants me to hook it up to the BES. If I can't get both to work, I may just see about ditching the BB as I really love my Dash too much to part with, especially with all the work I put into getting it on WinMo 6.1
Anyone out there tried anything similar? One other thing, I also have an iPhone that I want to be able to use too. That will of course be jailbroken so that I can use it with T-Mobile as I will never give ATT a dime of my money. I like the luxury of choosing what phone I want to use for a particular day.

WinMo and iPhone basically use the same internet settings, so you're good there.
The real question is whether your BlackBerry data plan gives you access to a regular WAP. I've never used T-Mobile, so I have no idea.
Surely your BlackBerry data plan is more than the data plan for a WinMo PDA, so just call T-Mobile CS from your phone and ask if you can use the T-Mobile MDA or Wing with your BB plan?

jailbreaking doesn't sim unlock your iphone, by the way.
the iphone's sim sanctity is tighter than fort knox (theoretically)

Can't respond to T-Mobile, But I use my blackberry for work sometimes, take out my sim card and put it in my ATT tilt regularly and use blackberry connect to get my e-mail...it works interchangeably on ATT but you need to provision your device every time you move the sim card or you won't get e-mail...

I didn't want to use BB Connect to get my mail, just Pocket Outlook with Exchange Active Sync. I can get my iPhone to work with T-Mobile, I was really concerned with making sure all three devices work without much effort on my part once I get everything setup. I guess calling T-Mo is the way to go at this point. If anyone else has done this with T-Mobile, I would be interested to know.

Some iPhone questions?

I know this is not an Apple/iPhone forum but I've seen a number of users on here that have or had an iPhone so I thought I would just ask some general questions.
Right now I'm borrowing a friends 2G iPhone to try out, still trying to get my SIM working in it without adding data temporarily, but that's a whole different story. Anyways, I also want to get an HTC Fuze and just switch back and forth between the two phones depending on which one I want to carry that day.
I am aware they both have their positives and negatives, I do not want to turn this thread into a WinMo Vs. iPhone thread.
My main confusion lies in the data plan. I would like to have data with both phones. Can I add the iPhone plan to my account and then switch the SIM back and forth and use the iPhone plan for data on the Fuze? or would I have to purchase the PDA plan from ATT for the Fuze, add the iPhone data plan when I activate it and then call and cancel the iPhone data the next day and just use the PDA plan for both phones? or would I have to purchase two separate data plans? In which case, it's going to be a very tough decision on which phone I get.

Not sure how it works in the states but here in the UK a data plan is attached to a sim so, swapping a sim from one phone to another shouldn't make any diference.
For example, I have a TD and an Omnia and I can switch between the two fine without any issues or cost.
To be honest, your best bet would be an Iphone forum as the winmob device won't care but, i'm not sure how the Ipony works ... does it use "apple" specific transport/protocol/ports etc?

Do you plan to purchase the two devices with a 1/2-year plan for each?

I plan on buying the 2G iPhone from my friend, so no contract obviously. The Fuze I plan on buying with a two year contract.
Any other iPhone users out there with some ideas?

Then, you'll be able to just swap the card among the two phones. I'm continuously doing the same between my iPhone 3G and other PDA's and phones.

So you just have the required iPhone data plan on your bill and it works with the iPhone as well as your other WinMo phones? So the easiest thing for me to do right now would be to put my SIM in the iPhone, activate it through iTunes, add the data plan. Eventually make my way to an ATT store to get the Fuze and just tell them I want a two year contract and no data, They'll put my SIM into the Fuze and then when I want to just go back to the iPhone swap my SIM into it?
Or should I go get the Fuze, tell them I don't want a data plan, they'll swap my SIM out of my current non-smartphone into it, then I put the SIM into the iPhone and activate it and the iPhone data plan?

Well, if you are on ATT, then as soon as you start using the iPhone with your sim, ATT will automatically change your entire plan (Calls + Data) to the iPhone plan, or atlest this was what was happening till a few months ago.

I had the 2g iphone for 13 days and I was able to use the 3g sim card and the data plan (not 3g though) on my stock att 8125. I think the main difference between plans is unlimited SMS.
I do not believe you can use an old sim to activate to an iphone, I might be wrong or outdated on this but my old sims and even my new one do not work with the iphone. I was told some time ago that only new 3g sim cards and the iphoen imei can activate for an iphone plan.
Am I outdated?

Well I'm on a family plan with my parents so I would hope it doesn't change the voice plan, only the data?
And what order should I activate the phones, should I do the iPhone through iTunes and then go get the Fuze or should I go sign the two year contract with the Fuze and then add the iPhone through iTunes?
If I sign a two year contract with the Fuze and then activate the iPhone through iTunes will they charge me the $175 ETF? I don't think they would since I believe the contract is for the line of service, not the device but I want to make sure?

Anyone got an idea on which way I should do it?

Your scenario is so specific that it is beyond my iphone experience. I think you should move over to the forums at wireless.att.com and ask over there. DARE I SAY...They are a good resource and has good depth of knowledge about sims/plans/iphone.
Maybe you can convince the 'Rents to allow you your own plan. Go to LetsTalk and get a free Fuze from Att. )

I cant wait for the iphone to come out on another provider...with a better data plan...

Touch Pro 2 on AT&T

Well I decided to leave my cyanogenmoded (5.08) G1 and try out the backflip.
Im miserable.
This thing is stuck in 1.5 (i dont think i can endure that for too long and q3 looks like too long lol)
Not to mention its LOADED with att crap apps..
AND
Now ive lost my $10 a month unlimited family data... with the G1 att didnt seem to care that I had that- now this Backflip is announcing- identifying itself as a smart phone to the ATT network... so it automatically changes my plan to the $25 a month within 24 hours...
200mb for 15 is not enough data... i will surely go over and frankly i think i could go over 2gb (lots of email and browsing... youtube etc)
SO
Will the Touch Pro 2 announce it self to the att network as a smart phone? Will any unlocked tmobile phone do that? I was told that the G2 Hero will not via another post but I am liking the look of the touch pro 2 a bit more- especially if I can port android to it...

Yes any TMobile unlocked phone will work with ATT just not ATT 3G. You will be limited to Edge. Same as taking an ATT phone and using it with Tmo. You will only see an Edge connection. 3G on ATT and Tmo are on completely different bands. Other then that the phone will work as normal. I'm surprised you were allowed to keep your unlimited data plan. ATT killed those off last week. New deals are $15 for 200mg or $25 for 2GB. You may want to call ATT and just make sure you still unlimited because if you just renewed they might has pulled a switch on you.

Well ATT did not let me keep the family data unlimited plan once I switched to the backflip...
I TRIED to do this quietly- I just threw my sim in the backflip and didnt say anything- but it sent me a text message a few hours later stating that it automatically signed me up for the 25/month data plan.
With the G1 it seems they (Att) did not know I was using a PDA - the G1 Did not report to the network that it was a PDA as the Backflip ( and I would assume any ATT PDA ) does.
What I am asking is- will the Touch Pro 2 (or any other NON-AT&T phone) act the same as the G1- could I tell AT&T that I am going to use my "Dumb phone" because I don't like the backflip (or what ever reason) - have them switch the Family data plan on for my line- and then put my sim card into a Touch Pro 2 and not have them know (as I did for the G1).
It would be nice if there was a list of phones that this is possible for... it would also be helpful if we knew HOW AT&T KNOWS that we are using a PDA - is it based on the IMEI number? Is there an android process or service or something in the background that announces it? Could we shut it down or change the ID number in such a way that AT&T's system would see a "Dumbphone" instead of a "Smartphone"/"PDA"
Just some thoughts...
Also- I understand that tmobile and att use different 3g bands and thus I would not get 3g- i don't care, frankly 3g is not that much faster than 2g (edge) any way.

No an HTC 8525 was the last phone I used where ATT or Tmo didn't pick up it was a smartphone and gave me the 9.99 unlimited plan. The HTC 8925 and up (TP2, TILT2, and HD2) all said "This phone is not compatible with this network, please call support to upgrade your plan." If I were you I would call support and blast the hell out of their ear. You should get the smartphone unlimited plan for $25, especially if you had a previous unlimited plan. All those are supposed to be grandfathered in. Tell then you never would have gotten the phone if you new you wouldn't be able to get unlimted data anymore. Its a new enough rule change they should be able to bump you up a couple support tiers and hook you up with the old unlimited plan. I know when they stopped doing the prepay plans they were calling accounts in for 2 weeks after the deadline until corperate said ok guys no more prepay its over. Then that actually quit selling it. So you should be able to get them to give you the proper unlimited plan. BTW what condition is your TP2? If its in mint I have a TILT2 I would be willing to swap. Then you would get ATT 3g. If you didn't know the TP2, TILT2, and Rhodium are all the same phone but different carriers.

Haha well the reason i was asking about this was because I wanted to see if I could use the TP2 on ATT with the 10 dollar family data unlimited plan... since apparently i can not I am not going to buy one lol :/.
At this point i need to find a phone that works on att, runs android, and allows me to use the 10 dollar unlimited plan without att recognizing the phone as a smart phone.
Does anyone have any suggestions? (other than the G1) Preferably something with a qwerty.
THANKS!

Not sure that phone exists yet, but who knows. I defenately know your not gonna be able to use your 9.99 data plan with any phones made in the past 3 years. They recognize the ime number and know its a smartphone now. ATT even puts what type of phone you used that month on your bill. I used his ATT sim card to unlock my phone, and he brought in his bill saying he used an iphone 21 days of the month and a Touch pro 2 for 1 week. I don't know why it said a week because it was more like 1 minute. But he said anytime he puts his ATT sim card in another phone it shows up on his bill as a new phone for a week.

Thanks- yeh its looking like G1 FTW!

Is there a hardware difference between the tilt 2 and tp2?

Yes, the TILT2 has a chrome bezel around hte sides where the TP2 has black alum. The KB is different too. The TP2 has an actual QWERTY keyboard with numbers on top. The TILT2 merged the nubmers into the UIJKNM keys so you have to hit a function button then the number. Also the TILT2 is just a touch more modern feeling and looking. Even the slider feels like a higher quality. As for the internal chips I beleive they are the same except for the radio chip for different 3G networks.

The radio chip was what I was interested in. If the HTC TP2 rom will load on either device, will that allow the phone to run on either 3G network? I'm a Fuze owner so I don't have the first clue. I just would like to know.

The rom will flash on either device, but the 3G will not work on both ATT or Tmo. You will have to pick one or the other. Tmo runs on 1700mhz and 2100mhz, ATT runs on 850mhz? and 2100mhz. If you use a tmo phone on ATT you will just get edge, and vice versa.

Don't quote me on this, but it all has to do with what IEMI's ATT has is its data base, thats how the phone tells the network what kind and make the phone is.
The Nexus one for att 3g doesn't show up as a smart phone.....yet

TP2 T7373 (SEA edition) runs on Edge with ATT. $15 for unlimited. I once put my sim into a Blackberry and they switched my plan to $25/m. I took my sim out, put it back in my TP2 and then called them. They asked me the IMEI # and switched me back to the $15/m unlimited (MediaNet). Hope this answers your question.

HTC TP2: Cm7 vs WinMo
I do not know whether to turn to you below: : Confused:
Recently, they have gained from a TP2 that already had android 2.3.7.
I want the phone to 7.2.0-RC1-Hero Caynogenmod was changed back to WinMo, but only forum I read that the WinMo on how to make android (or next)!
Very slow and unstable for mal (as iron is not present).
Please help me, especially in how the program could be "android HTC TP2 is connected to the PC to WinMo to make him know what to do, and then step by step.
Important! : Sírás: (not just the android to WinMo on the card next to it alone!)
(I want to stay next to the robot, but if more than 2 of the stability and the "speed" of the WinMo is OK!)
A big thank you in advance for your help! : Good:

Dude this thread is 3 years old, post in the touch pro2 section, type is name in search device box on top.

Am I able to use Atrix 4G in AT&T network without any data plan?

I am a AT&T prepaid user. Can I use the Atrix 4G in it without data plan? I only use Wi-Fi which is much faster.
The AT&T shop assistant man told me that I will not be able to use it if I do not open any date plan. If I am a prepaid user I can not use the phone; If I am a postpaid user I will be notified to add a data plan after I insert the SIM card into the Atrix 4G which is a smartphone.
Currently I also use a smartphone in AT&T network and does not commit any data plan. The phone works great. The shop assistant said the reason is that Atrix 4G is a AT&T phone and will be recognized by AT&T and force to open a data plan.
I do not know whether I should believe him for may be he is just trying to sell me more expensive plans. Is it technically possible to ban prepaid users? Is there any way to avoid this restriction? Since the Atrix 4G smartphone is bought in full price and unlocked, I do not owe AT&T anything. It works in T-Mobile, but does not works in AT&T prepaid, which seems very rediculous.

You may use any phone smartphone that its not ATT branded.
But if the phone is a ATT branded they do detect it using the imei and force you to add the expensive data plan. You may run a few months without been detected, but sooner or later they find out and force you to change plan.
I know this for fact because a used to use a Xperia X1 that came unlock from other carrier on ATT, and they never force me to change plan, but as soon as I started using an Iphone on the network a few weeks later I got a txt msg telling me they detected a smartphone without data plan, and automatically added the data plan.

You can modify in Setting-->Wireless&network-->mobile network-->Access point name. After that, you can set user name, add, pass follow your mobile's network service. Good luck.

have beeen using a atrix since march and have had a iphone since 2g on att using my sim with no data plan. just put the sim in and off you go almost 5 yrs now, and no forced data plan.

[Q] Nexus S i9023 willing to use ATT without Dataplan possible?

Hi guys been reading on forums about att automatically detecting smartphones but some say its ok if the phone is unbranded and some say any phone it might be ATT will be able to detect it...
My Question is
I have a Nexus s i9023 bought in india now i am in USA i already bought an ATT connection which i am using on a samsung [dumbphone](i activated the sim with the imei of that dumbphone) ..I would like to know if ATT will be able to detect my phone as smartphone if i switch that sim onto my Nexus S and activate a dataplan??
PS: i will disable data by all means...using CM7.1..will use Wifi only

HI,
When I was in US last year - I purchased multiple connections - initially from AT&T and then from T-Mo.
AT&T - My phone was a Nokia 5230 then and I threw the dumbphone into bin and used my 5230 without any issue. I was on a $50 plan with unlimited talk & text and 500MB data.
T-Mo : Same experience, this time I just bought a sim. Not even a dumb phone. You can walk into any of the T-Mo showrooms and get one. Or buy a dumb phone + plan and use it..
As a matter of fact, I have a friend in US who is using a Galaxy S with a T-Mo sim taken out of an dumb phone.
Thanks, J

hey thanks for the reply!!
Well i know abt the scenario of t-mobile... i would like to stick on to att... so i wanna know if att would be able to recognize my mobile as a smartphone and charge me a dataplan accordingly...

NP man.. Hit Thanks if i helped
I don't think so. Are you on a postpaid plan?
I just confirmed that you could get the Sim only connection from AT&T too. Prepaid connections are generally bundled with dataplans and they stop working once you cross the limit

Thanks man...
My ques is if i swap the sim does ATT automatically recognize nexus s as a smart phone ?? coz of it does it subscribes to the dataplan into my account...:|

yes they will detect your phone eventually.
if you are under contract they can enforce a data plan requirement
i was looong off contract when i switched to a crackberry
but had data blocked on my account
they never tried to force me onto a data add...
fwiw

we threw my old captivate on our sons dumbphone line, turned off data on the phone and AT&T has not said a thing. The account shows the smartphone on it, but no data plan is being forced.
