"will it can display the two sim celphone numbers at the same time?" No. "can i connect it with tmobile u. s. a. internet data in 3g speed and functions?" No. It'a a dumbphone, not a smartphone. "does it includes extra batteries?" No. "does it has a silicon case or hard rubberized case?" No. "and the os, what os system does it use? like the blackberry os 6.0 or windows mobile pro os?" A proprietary BLU OS, nothing in particular. Again, it IS NOT A SMARTPHONE! You don't get unlocked smartphones running BlackBerry OS6 or WinMo for $30! What you get for $30 is pretty much WYSIWYG.

Dear friend, Thanks for your inquiry. This phone can just support 2G network: GSM 850/900/1800/1900MHz. If your sim card meet this condition, you can use this sim card for this phone. Meanwhile, we suggest you can check the link of this phone: http://www.amazon.com/gp/product/B00GT68AVU. Which can support Support 3G: WCDMA 850/2100MHz and 2G: GSM 850/900/1800/1900MHz. Might this phone will meet your expactation. Thanks a lot.

This phone supports both 2G and 3G . The network it supports as Dual SIMs WCDMA 900/2100MHz (3G) GSM 850/900/1800/1900MHz (2G). It means if the provider can support those network . Then this phone works .

To add to the mismatch of information - the Amazon specs for both the A01US and A03US models (64GB and this 128GB) - don't mention the WWAN (3G) capabilities, but the photo of the left-edge clearly shows a clearly-marked SIM card slot (labled "SIM", with a sim-card icon). I've read that it won't be the same AT

It can use 2 sim cards at once. It works fine with just one though. It is supposed to be able to work worldwide but we haven't tried it yet.

Mine has 3G and sometimes I make calls from it. However, because of its size its too bulky except when you are comfortably seated or using earphones.

*BE CAREFUL* the link took me to a model that lists 3G data. If true, this model is OLDER *DATA* protocol, not the newer/faster 4G nor 4G LTE, even though it lists CDMA, TDMA, GSM and AMPS. There are newer, just released 4G Wilson electronic models just announced about June, 2014. Go to the OEM website first and look for 3g v 4g (lte). You need to check each device's *DATA* frequency MHz AND transmission mode/protocol (3g, 4g, 4gLTE, CDMA, GSM etc.). Carriers have different frequencies / protocols their systems are designed to support. If all your phones use the same *DATA* frequency, there is a higher likelihood of compliance. As for 'simultaneously' I cannot answer that because some electronics are designed with 2-way simultaneous support (send & receive) whereas others will only do one mode at a time - per device. That is why some of the newer wireless access points are touting 2-way support, they can send/receive simultaneously so more than one device can be served concurrently. Contact Wilson Electronics (OEM MANUFACTURER TECH SUPPORT, not the WILSON retail reseller customer service) for absolute answers. Be aware many of the older Wilson Electronics cellular amplifiers (such as 3g) only boosted *DATA*, NOT *VOICE*. Check the model that is most compliant for your 3 phones as some of the *newer* 4G models are supposed to boost for voice & data. Also, Verizon phones in US I have only been able to get to function within this country using their 4G LTE mode, NOT GSM (which is what AT&T, others might use) even if the phone is dual or tri-band. Unfortunately if you notice there sometimes different product booster model #'s in the past for AT&T vs Verizon because of the above so if your phones are using inconsistent transmission technologies, one mobile booster device may support most but not all of your phones

Yes. That's absolutely right. Currently, I utilize two sim cards from two different providers at the same time. Both sims (with their respective numbers) are active at the same time and I have had no problems making or receiving calls from either.

If you get one that is not defected meaning both sim slots work Yes both will work at the same time meaning you will have two sim cards in the phone at the same time but different numbers. You can receive calls and make calls from both you only switch from sim1 to sim2 each time you want to make calls its your choice now depending on what number you want to call from. It is very easy and nice if both sim cards are working but one of mine didn't work.

This phone provides 2G: GSM 850 / 900 / 1800 / 1900 (SIM 1 & SIM 2) 3G: HSDPA 850 / 1900 / 2100. This version does not have 4G capabilities.

No, the phone can use GSM network with your sim card, but it can not use 3G movilnet.

Hey, Lenovo A830 supports 2G：GSM 900/1800/1900MHz 3G：WCDMA(UMTS) 900/2100MHz

Good question. I thought this was the one with a 3g Sim but the specs show the same the cheaper one. I have ordered the cheaper one.
