3G modems on G-tab

Anyone tried connecting a USB 3G USB dongle with the G-tab? Will they work?
I'm thinking of getting one of these to put inside my G-tab if I can find a place inside that will fit.

You know, I think this might be possible.

The specs on this Android tablet (I think its the ZPad?) claim that USB 3G Modems are supported. It even lists the specific models.
EDIT: This is one of the models listed on the specs page. http://cgi.ebay.com/ZTE-CDMA-REV-A-EVDO-Modem-Model-AC-581-/330492290336?pt=LH_DefaultDomain_0&hash=item4cf2e02520#ht_2134wt_1139
EDIT 2: Well I messaged zetronix through their website and left a message on their support number. We will see what kind of a response I get. ^_^

I plugged my AT&T USB 3G modem (Mercury) into the device and nothing happened. Nothing showed up in "wireless" settings. Don't think it works with TNT-Lite.

pls feel free to try your 3g sticks against my kernel offering.
pls snap some dmesgs, and give me the chip/device ids if it does not detect it, and i can add them in.

I have an air card that I will test. If I can get this working, I would be a very happy sysadmin. It shows up in dmesg, even with stock, but from there nothing.

1. Build a kernel module.
2. Configure kernel to support wired ethernet via the kernel module.
3. Insert module.
4. Configure the GTablet to use the new network interface.
I considered doing this to use my iPhone as a USB network interface, but the adhoc wireless network support from MyWi 4.0 was good enough.

That would be really cool especially with the newer 4G usb modems being offered by my carrier. But for now I simply use Wireless Tether on my rooted Droid X and use the sweet unlimited 3G to access the internet via wi-fi on my G Tablet.
Since I already have to carry the phone around and I have an unlimited data account it seemed like a good idea.

This but with my Evo... .
But I do understand how some of you get corporate data plans with those usb sticks... It would be nice for you to use

Has anyone managed to get this to work, I was at at&t today and almost got an aircard (3g Dongle) today but wanted to research a bit.

[Q] HSUPA and Data on Captivate Help

I seem to be having an issue with my data and am trying to narrow down the reasons for my problem. The issue is I CANNOT use HSUPA (H) for data, I always get a connection timed out issue. I put the phone in 2G GSM mode only and have data working, but of course I was spoiled with better speed I can't stand it.
My question is if AT&T could be doing upgrades to the towers in my area, will that affect my speeds, or is something broken internally in my phone. When I select WCDMA mode, it takes FOREVER for it to connect and says searching for a long time but does connect or displays (H) with 3/4 bars of signal. My friend has an unrooted captivate on 3G and has no issue with data. Does anyone know the cause of this.
I have tried a few different modems (jl3, jk4, kp1....) all the same and have tried 2 different OS's with same data timed out issues while trying to use (H). I am currently in the process of flashing back to stock to see if that will resolve the issue. Thank you for your time guys.

H doesn't necessary mean HSUPA. It simply means HSPA (HSDPA only or HSDPA and HSUPA). You didn't mention anything about your firmware but I guess you are experiment with non-Captivate firmware and modem combination trying to get HDUPA working. From what you described, it seems your current firmware and modem combinations lacks 850MHz support for 3G (most European firmwares lacks 850Mhz) and your local tower happens to use 850MHz, not 1900Mhz. Just a guess.

Make sure you have the modern set to proper frequency (WCDMA 850 or 1900) for your area. The modem thread can tell you all about how to do it.

Sorry guys, I guess that was an important part I forgot. I was running Andromeda and thought the same so tried Cognition 4.1.1. Also after going to stock 2.1 I still have the data issue. I can connect to wifi just fine, but no using ATT data will work.
I called customer service and walked through the steps as usual and after some looking into my area, he said there were 3 towers reporting severely degraded. It just sucks seeing my friends phones working with no issues. He said that repairs are stated to be finished sometime in the next few days and to call back later in the week if the problem persists.

Looks like you tried both i897ROM and non-i897 ROM, so it's not firmware related.
Did you try to put someone else's SIM into ur captivate? How about some other devices in ur area?

I didn't think about trying my friends sim card. I will test tomorrow morning. Ty for the idea to isolate the problem to my phone!

umm not really related to your phone. but im suggesting its the tower upgrades getting them ready for 4G that is causing your phone to act up. i have a HD2 and we have 3G down here. but since early march i get nothing but EDGE. what happens in the month march? AT&T will be launching 4G in selected markets. it was confirmed once i was talking to a AT&T tech. so im just waiting to see what happens in the end of this month.
NOTE: it could also be your sim card having problems. AT&T replaced mine thinking it was a problem with the sim card since i have a AT&T native W350 and i was getting the same problems. call them up again and ask to talk to a tech and tell them your having a problem with your sim card. they will set you up a appointment at a corporate store. free of charge.

I did not think that the Captivate's hardware was capable of HSUPA?
Is it?

you would have data, but no voice

Sorry for nor replying sooner. My 3G data seems to be working again. My lack of in depth knowledge is why I put the hsupa above when my phone displayed H I didn't know what to call it.
It must have been tower upgrades. I didn't restart my phone and left it on the charger overnight and the next morning I had no issues. I did a reboot of the phone as a test and connected with data with no issue. Too bad as I was close to getting a replacement, though it would suck and be my luck to get one with other issues. Mine is a 1007 and works perfect (other than the obvious GPS.)

[Q] question about sd card slot and 3g (not 4g)

hello all
about sd card slot, as i see in forum, it's not usable yet. why? that is a lack of hardware and will be usable after 4g upgrade? or it's just a software issue and can be used with hacking android?
and another question, the 4g will be available after hardware upgrade. how about 3g? is hardware needed for 3g , 2g (gprs) installed on device? i mean is it possible to use 3g with hacking software or it's lack of hardware
thanks in advance

4G is a pure hardware issue. Hardware changes need to be made, that is why the 4G upgrade, when it happens, will require the Xoom's to be brought into service centers. Nothing you do to the software can add 4G.
As for 3G, it is also a hardware question. If you bought a 3G Xoom, you have the proper hardware for 3G...if you bought a WiFi Xoom, you do not. No hacking possible or required.
If you want 3G and bought a WiFi Xoom there is a very easy fix however. Put the WiFi version on Ebay or give it to someone, and go buy a 3G model.
Quick and easy, all fixes should be like that.

Then I would suggest checking with your carrier.

Im from iran. Here we have not 3g carrier yet. Both operators here are 2g network. The carrier i use, the network is EDGE, cannot i use mysim card for gprs internet? Just like gprs in htc.
And also in setting, mobile network, i see an activation. What is that? I didnt activated yet. Is it activation for verizon carrier just in us?
For using other carrier device should be unlocked like God dang iphone or ... ?

stock browser
Also another question. I installed a few browsers but the best browser is the stock. The only problem with it is typing, for example just now, i'm wroting this o xoom but writting speed on stock browser is very very slow
What is the problem? Is there any solution? Or any better browser?

also i forgot to say that my rom is stock rom and not rooted yet

Typing lag is a known issue on the Xoom. Are you running 3.0.1 or 3.1? Most people say it improves with 3.1. YOu can also try rooting and installing one of the custom kernels with overclocking, either Tiamat or Launchpad. The Tiamat kernel cleared it up for me, even with moderate overclocking (1200 on mine, usually).
Lots of guides here to help you upgrade, root or install either kernel.

I can't say for sure, as I have a WiFI only model. Likely the Activation option is relevant for Verizon only, but put the SIM card in and choose the option, see what happens. I would assume that if your SIM card is legit, then it should work on the Xoom, but this is unknown territory for me.
Anyone using a 3G Xoom with gprs?

i use my sim card with my htc hd2 (android), i'm using gprs a lot on it

and how about sd card slot, the reason it doesnt work is lack of hardware or can be done with software hacking?

The lack of an SD card is a software issue. Use the Tiamat or Launchpad custom kernels to enable it.

4g LTE SD Card?

Just wondering if there is such a thing? We all have wifi tablets but i'd love to get an SD card that allowed you to insert your sim card into it that would allow you to essentially have a LTE tablet? a plus would be if it had 32gb of memory also
anything like this exists?

i dont know what came of it but TMoblie here in the UK when they first mentioned their 4g plans said there would be a sim/sdcard (i forget which) that would have a 4g chip and antenna or something in it to make 3g 4g... never heard of it since though
Sent from my ASUS Transformer Pad TF700T using XDA Premium HD app

An interesting concept, but there's not a single mobile provider who's going to let it pass into retail sales. Because if we could turn our devices into 4G by means of an SDcard, they'd miss out on all the oncome from all of us paying for another new phone/tab.
Also, you'd need a 4G data plan, anyway.

Definitely a cool idea, but never heard/seen of one. I was in the AT&T store yesterday, they have an LTE wifi hotspot device that was pretty cool, only 49.00 and would accomplish the same thing...

The TF700 doesn't have any radios for 4g unless your saying those would come in the SD card. I know they make USB sticks that will pick up 3g / 4g (at least I think) so maybe something like that would work

Don't count on it. It's more than just a sim to make it work with 3/4G. You need at least an UMTS module and an extra antenna. You should have bought the LTE version instead - you will never get "native" 3/4G on your non-LTE transformer.

In theory this is possible - there exists an interface that's electrically equivalent to SD, but supports much more than memory cards. It's called SDIO (see wikipedia article, I can't include links). Since the transformer supports 4-bit SD interface, it automatically supports SDIO. The only problem is the drivers.
Here's where practical problems start. The Linux kernel includes very few drivers for SDIO devices. So even if such device exists, Android would not be able to support it.

You've probably solved this by now. I rooted my Evo 4G and use the Cyanomod 7.2 tethering feature. It works great. I use my sd slot for data2sd.
How did you resolve this?

i would love to have one of those

ibiesio quick
That woukd be kinda cool, but I already pay for the fantastic privlege having (no to barely any) service for my phone (sprint. As someone who switched from verizon to sprint, DON'T. Huge mistake). My phone is the reason I dont take my tablet out of the house (where theres wifi) unless im going on a trip. I assume thats how it is for most people, which is why there most likley isn't a massive market for it. I could see it being useful to people who use tabs on the job and travel. Even then, nowadays theres wifi pretty much everywhere. The added security of 4g is a plus, though. VPNs are nice but are often slow and cause issues with google and such.

[Q] 2 week trip to Scotland - best prepaid options?

Hello all,
As the title states, I'm taking a two week trip to Scotland in August. I require "local" voice/text and internet (unlimited?) would be a HUGE plus (especially for gps use).
T-mobile seems to have a $42-something plan which includes all the above, but I would be upset if my phone didn't work well with it for some reason when we landed. I'm currently on AT&T running Cyanogenmod 3.0.66? and Slimbean 4.2 and very willing to reflash to more appropriate roms.
My questions are:
1. Is it reasonable for me to bring my S2 and use a prepaid SIM, taking the risk something may not work? If so, what kernal/rom is best for Europe (say T-Mobile, etc) ?
2. Does anyone have a better option? This is my first time abroad and I'm open to advice.
I haven't been on xda for a while, so I apologize if this information is generally available. I did attempt to search but couldn't find what I was looking for.
Please help this old man!
Side question: Anyone have a good experience to report with an offline gps app?

Use a rom which supports GSM so go into settings mobile network and then network settings and see if you have WCDMA / GSM. That means it will work here. Also the best and cheapest sim card to get here is a Giffgaff one.
Also, regarding Gps, it's Scotland... You won't get lost.
Giffgaff give for £10 unlimited texts, 250 or 500min call and 1gb data... So just use data with Gps.
There is a cut down version of that for £5 but I'd rather have more Internet to use maps.
You can convert the £££ into $$$

If T-Mobile in Scotland uses the same frequencies as here in the USA, it would be reasonable to use the stock tmobile UVMC6 plus skyrocket JB kernel plus either UCMC1 radio OR UVMB1(blaze 4G radio)
Here's the rom,I used it on my rocket for sometime
http://forum.xda-developers.com/showthread.php?t=2344942
But you have to flash a skyrocket kernel to correct screen rotation..Mohan has one in the dev section
Search for UVMB1 radio for data on AWS at HSPA...I don't think the Scottish have LTE on T-Mobile yet or even UCMC1 would work on their data if the use 1700/2100 AWS on LTE...
Have a nice trip...Scotland is a beautiful country...

I agree, however will this work on my current AT&T provider until I land in Scotland? This is my primary cellphone.

The rom, yes...
The radio, if you use LTE here, it will not work on UVMB1, but HSPA is ok
My plan would be
1.Flash the T-Mobile rom now
2.Flash the skyrocket kernel now
3.Leave your radio alone..
4.Have few T-Mobile radios like UVMB1 on your sd, flash it on board at the airplane do it would be ready there...
Of course that's if you choose to go with tmobile path...

Thank you for your quick reply. I briefly looked into Giffgaff, and it seems like they charge for anything not between other Giffgaff users. This would make calling hotels, etc still costly. Plus, it looks like I need a UK postcode to receive a SIM card.
Also, we plan on doing some driving all throughout Scotland and the GPS option would greatly decrease any stress related to traveling, but thank you for your reassurance! :fingers-crossed:

Use the £5 or £10 goody bag. You can call anything in UK. Landlines, Mobiles and all. They don't care.
You can get the sims at shops too. Just the websites says post code.
250 or 500min is to landlines and whatever. The Giffgaff to Giffgaff ones are free.

It is good to research on network options while you're here...But probably you'll find a cell phones shop in the airport and buy a SIM from there..
Go to Wikipedia and read about their network bands, if they are compatible with AT&T specifications, you might need nothing done and your phone would work right away as soon as you put the new SIM and setup the correct apn...Of course that's if your phone is already unlocked..
By the way sir, this is the general section, all questions should be in Q/A forum...
