[Q] U.S. GSM Tabs: phone capable?

---

it's been brought up in other threads, but I'll get right down to the meat of it: Are the US variant tabs capable of sending and receiving cellular voice calls and texts, hardware wise? In other words, is the hardware there and just disabled by software, or are they physically incapable of this function?

Im on Sprint now, but my goal is to switch to T-Mobile or ATT so I can swap sim cards from my phone to a Tab at will. (yes, I know the tab takes a micro sim, but there are adapters). If the cellular radio is left intact, then rooting and flashing new firmware could enable it. Am I right?

I don't think anyone truly knows if the phone functionality can be re-enabled on the US Tab, but are you sure the US Tab uses micro-SIMs, because the European one just uses standard ones?

Engadget reported that some T-Mobile US customer have been sent microSIMs recently, which lead to a spate of rumours about the iPhone4 but it was supposedly then confirmed that the microSIMs are to do with the Tab instead.

I spoke with T-Mobile tech support early this morning... the tech said according to the trouble shooting guides that they have to use... the hardware is there, but voice has been disabled due to software restrictions. If you look on the product page on the T-Mobile website, the specs listed have all 4 gsm radio frequencies as well as 2 aws 3g radios. The display pic even shows 4 full bars of cellular reception. The tech said voice was not supported at launch... however if the phone was "hacked" (his words) technically it could be used for voice and data. He also said that the data plan for the tab is the android smartphone plan, so if you do flash a new rom and have the unlimited plan... you should be gravy for voice and data!! I hope that all of this turns out to be true... we shall see in the next 2 days.

thanks for the info, im already a tmobile customer and want to do the same thing, flash cyanogen to the tab. I have a nexus one and this would rule. my only other question is...can i use my full upgrade on the tablet? i spoke to a 2nd lev tech support and he said i might have a problem doing that because its tech. not a phone. the regular rep couldnt help me at all, she had no info until launch....didnt even know launch date. again can i use my tmobile upgrade for the tab....

Sounds good

IF this were true, and the hardware is all the same, then that would also lead us to believe that the EUR version should have 850 3G capabilities too then, should it not?
I find it hard to believe it is a software limitation. I HOPE it is but highly doubt it.....fingers crossed

No.

Rumours are that the T-Mobile US model uses a microSIM.
If that's true, then there must be some sort of difference in hardware between it and the EU models.

Not necessarily - the Telus Desire and "regular" Desire are essentially the same but have different radios to support different bands.

Just came back from demoing the Tab at my local tmobile store. It does use a standard sim. However the update is this: in the apps management screen, it seems that the only thing missing is the actual phone apk. The phone utility apk is there and the contacts apk is there. It looks like we just need the phone apk and then possibly the contacts merge apk to get voice enabled. Anyhow, the phone is being released at 11am pst tomorrow in my town, mine is on reserve so I will have it by 11:05am pst. anyone who wants to guide me into activating voice on this baby, send me a message and i will be happy to assist with trying some methods out.

I will need to try the following apk's from the euro version:

phone.apk
contactsmerge.apk

oh, the local reps looked on the computer and said that this device WILL require a webconnect data plan, not the unlimited android. There is a work around though... with voice enabled, you can call tmobile and ask for a tech support supervisor, open a trouble ticket and request an engineer to change your device ip range to that of a smartphone... then data and voice should work together. I had this problem on my aws version of the dell streak and it fixed it using unlimited voice and unlimited android data plans.
