How to enable 3G/4G on A500? - Acer Iconia A500

I am researching for set new tablet and A500 in my mind. But I only confuse with 3G connection. I wonder if 3G enable I will take it immediately. Anynone tips or tricks to enable this. However USB 3G model Huawei E173u-1 can be using as replace but I need an perfect slot sim card inside instead of single USB 3G

There is no 3G on the a500. It just shares the same OEM, BIOS and case as the up-coming a501. There is no SIM card hardware in the a500. Even if you went so far as to crack the tablet open and solder a sim connector, there's no guarantee it would work.
thor2002ro started developing a USB 3G options for the a500 but I'm not sure how far it will get and it's certainly not supported by Acer as it will likely require root.
If you need 3/4G - get a 3/4G enabled tablet. The a500 is WI-FI only.

A501 will coming soon in Q2 as notice from AT&T maybe in this summer. Does slot sim card for any sim size or only engage with AT&T? I live outside the U.S and my network provider just only 3G band. I afraid that do not compatible with size. It had better be in the size with same standard slot for all.

[PREMOD] Modding Motorola Xoom Verizon for speaking HSPA+

I'm on the best way, here the facts:
1.) Crossflashing Xoom VZW with the System Image(Tiamat Kernel as boot) of European 3G Xoom is working fine after fastboot -w (complete wipe)
2.) With a firmware upgrade of Atirx 4G CDMA we saw, it is possible to reconfigure MDM6600 for GSM
3.) Simcardslot is working fine with GSM Simcards
Hi all,
Yesterday I got my Xoom. I'm how you see from Austria(Europe), but I ordered it from over the sea because I saw in a teardown, that there is a MDM6600 chip built in.
Now I have it, HSPA is not working, but should only be limited to CDMA by the firmware.
I would like to change that.
My first idea is, to search for MDM6600 driver sources, compile them for the tegra and replace the existing... but this expect, that the limitation is in the libril and not in the kernel...
Any thoughts to this topic?
edit: stupid me, first of all would be nice to take a look at etc
someone has an idea what the location.cfg is, and what the flag DL_LCS_NETWORK_3GPP (set to 0) are doing?
Kind Regards
Ralph

I have no idea how to help but I sure would like to. If there is anything I can do let me know I'm all set up to do all kinds of stuff I just would not know where to begin.

Just 'cause the chip does both modulation schemes doesn't mean the appropriate antenna-interface hardware is built into the device. They put a 6600 in there 'cause they fully expected to push out a GSM version; I'd just wait for that one.
concerning the antennas(from www.motorola.com):
CDMA 800 /1900 LTE 700, Rx diversity in all bands
would be a bit funny, to use a multiband chip, to need not to produce different devices, but differ by the antennas
regards
Not to mention the fact that there is a place to stick a sim card in no the top of the device
Sim card slot is for the lte upgrade...
The SIM card is for LTE in the States, but again- just 'cause the chip is in there doesn't mean the US-spec Xoom has the requisite hardware (not to mention the proprietary Qualcomm modem SW) to let it run on GSM in the versions shipped in the states.
When we make GSM handsets at my clients, we even have to make separate hardware for the I, II, V-banded stuff (AT&T) vs. the I, II, IV-banded stuff (T-Mobile), and that's all with the same chipset.
You are going to need to take a good look at the NVM and amss.mbn(radio baseband image) in order to make this work.
Have you used RadioComm to read and dump the NVM?
That would be an excellent place to start. Unless of course, you had access to MDM6600 GSM radio images and source code...
I don't have even the slightest knowledge necessary to be able to contribute to this conversation but I do know that I am planning to go out the country for quite a while and would love to be able to connect to a wireless data service of any kind. I will be in a country with cdma also but of course it is not verizons.
If what you are trying to do works I would happily try to donate something out of appreciation. The idea of my xoom working with gsm networks would be more than a dream come true. I wish you all the best. Let me know if there is anything I can do (I know there isn't though, I really dont know the first thing about modding other than that the modders are awesome!)

Good Morning,
There is something confusing me, and it seems I've to think about something I cannot imagine actually.
So my big stupid question:
Do you need a simcard to connect to verizon's cdma network?
And if not, how are you athentificating in the net?
Regards
Ralph
CDMA authenticates to its network via the combination of the MEID (formerly known as "ESN") and the MIN, both of which are hardwired into the firmware of the device.
Ok, so the device is authentificating, but from where do the network know that you are user xyz? In gsm networks because of the simcard id, and in cdma nets?
Sent from my Xoom using XDA App
They associate the MEID/MID/MIN to your account.
For example, they scanned the barcode from my Xoom when I bought it and added it to the Verizon account they had already finished setting up for me. Once I got it home and hit the "Activate Device" button, the device got on the VZ network, where the setup information (the phone number, PRL, etc.) got downloaded to the CDMA 3G radio. But all that happened 'cause the VZ servers were already set up to associate that MEID to me beforehand.
ouch, that means there is a massive firmwaremod needed so that it can use the simcardslot for auth...
ok, please tell me what you know about how transfering the data from the sim to the chip works (bookmarks and so on)
do the ril-daemon play a role?
thanks

Now no sim card is used to connect to Verizon's 3G network. The new 4G Lte network will use a sim card, but that has yet to be activated. At present you connect to Verizon's 3g network through the cdma radio which needs to be registered and then activated by them, but it does not use a sim card.

The sim card slot is a dummy slot right now, there are no electronics in there that can even read a sim card right now. When you send out the Xoom for the LTE upgrade they will put a real modem in there with the sim card slot. It is PHYSICALLY IMPOSSIBLE to convert the Verizon Xoom to GSM at this point in time.

Key words: "...at this point in time."
That may change once the hardware is in place for the SIM slot it MAY be possible to build a radio image that can access GSM/HSPA bands.
Not easy, but not impossible.

You would also need to modify the antenna to pick up the correct frequencies, they usually aren't on the same band as CDMA. For example VZW is the only carrier going for a total 700mhz 4G network.

That's almost correct. There's a working, active SIM-card slot that's hooked up to a serial port on the CPU; reading a SIM card right now would just be a matter of some (extra?) software. What's physically missing is the actual LTE modem, and there's a dummy card in the mini-PCI slot right now.
But that's not why it's not possible to turn the current device into GSM; as noted in this thread before, there's a lot of other things that'd need to be there, and just 'cause the 6600 is GSM-capable doesn't mean it's a simple, software-only modification. Even if it were, good luck getting the customized baseband software from QCT for it.

Cheapest WiFi hotspot devices for my A500?

To be connected when away from home or hotspots, I need a mobile WiFi hotspot device which will use my GSM network sim to access the data connection. The device should be portable enough to keep it in my pocket. Please recommend some such devices with links to where I could buy them.
And if there are any other reliable way to be online without using the WiFi, please do mention it.
[Solved] I found A 3g wifi router that supports usb 3g modems.
What type of mobile phone do you use? Most of the newer Android phones allow you to use your device as a mobile hotspot. I use my Samsung Galaxy S as a hotspot now and then and it works great.
I believe there is a thread here covering the use of 3g devices that plug into the usb port. Search on 3g + usb and you should be able to find it.
Best of luck to you.
Just a guess, but seeing your country (Bangladesh), this will be something that will be specific to your local wireless provider that you will probably need to investigate yourself. Like, I can't tell you to go T-mobile or ATT (the US GSM Providers).
ifox Mifi-30....
http://www.ifoxonline.com/product/product.php?CategoryID=2&subCategoryID=7&ProductID=25
is that you look for ?
just sell your old phone and buy a samsung galaxy mini (you want the cheapest right?) ...
i believe it can be a hotspot...
then you are good to go, no need to bring extra thing in your pocket..
Ok, as far as I know MiFi devices create a WiFi hot spit using a network connection. With the model you recommende, can I plug in any kind of GSM sim in it?

SIM Slot on Verizon XOOM?

Quick question, I was close to purchasing a Xoom for work reasons (going on the 5gb data PAYG plan). Boss decided to give me the Panatech 4g USB radio for use in my laptop and have the company pay for it.
Would I be able to purchase a 3g enabled XOOM and pop the verizon 4g SIM card into it - with the understanding that I would only be able to access 3g speeds?

AFAIK the Sim slot is not active, it has to be sent back in to Moto to get the 4g hardware installed and the sim slot activated. It was suppose to happen not long after release but it has all gone quiet on that front.
Lordao
Verizon 3G is CDMA and does not use SIMs, instead using the Xoom's MEID (AKA "ESN") for identification and authentication to the network.
So as lordao said, the SIM is inactive now (as there's not even a 4G radio in our devices yet). Had you asked this post-4G upgrade, then the answer would have been "Yes" instead and you would have also had 4G speeds, too.
Thanks, that's what I was guessing as well and just wanted to check on confirmation. I would hate to have another expense and a 3rd mobile device with a payment due every month (Tmobile g2x with unlimited data, the usb 4g modem AND now a xoom? no way). I've had my heart set on a android tablet but I don't really want to lock myself into a wifi only device. Would love to have a tablet that I can keep my 4g sim in and swap out to the usb when I need to access the internet on my laptop.
I'm constantly moving from site to site for my job, this is killing my cell phone's battery ( I carry 3 batteries). Hoping to knock the cell phone down to personal data + voice and the xoom for email / vnc / google docs, then busting out the laptop for issues I need a full keyboard and full OS.
I've gotten my job down to the point I can do 90% of it from a tablet (logmein...google docs... etc), was dead set on buying a xoom and paying the cost per month, but having the boss suprise me with a 4g usb threw a monkey wrench in my plan.... not that i'm complaining at all
If you buy a $100 Cradlepoint CTR500 router (make sure it'll work with that 4G stick, though) then you can have LTE now, and if you get the $150(?) PHS300 it has a battery, too.
i second the idea of a cradlepoint phs300 router. Plug your 4g USB, and your good to go. On its internal battery, you get 2hrs, but if you get a car charger for it. Well you can run the router from the cigarette lighter, and if you have to you can unplug it and take the router with you. The phs300 hardly weighs a bit. Get the carry pouch for it and carry your modem in there too.

Moving Verizon LTE SIM between tablet and USB modem?

I currently have a Xoom tablet with a data plan and figured it be nice to have an LTE USB modem as well. Just curious, but has anyone tried moving the LTE SIM back-and-forth between these two devices?
I don't even know if USB modems have a user-accessible SIM though (don't own one yet).
Any thoughts?

depdends on the class of sim cards...
example...
if its a 3g sim..
should genereally work for all 3g devices,,,
Some of the LTE USB Dongles I took a look at have User Accessible SIM Cards. So, they should fit right in. Also, I don't think you'd have and problems since both are only using data.
Just do some shopping and find yourself a nice USB Dongle that allows you to access and change the SIM card.

Verizons LTE SIM cards will be LTE only since they don't have any pre-LTE GSM networks.

I switch SIMs all the time between my LTE Xoom, my Novatel 4501 USB stick, and my HTC Thunderbolt. One SIM has a much larger data plan on it than the other and I use it in my USB stick when I'm away from home and need the data (or I just tether out of my Xoom- VZ didn't restrict that in the SW).

[Q] where can i find the 3g connection?

hi, i boughty recenlty thinkpad tablet 10.1" with physical buttons on its side! i have put my sim card! but i cant find where i can use the 3g option????????
thks a lotttttttttt :crying:
No one??
Hi.
Please notice that there Thinkpad Tablets may or may not come with the internal 3G card. The slot of putting the SIM card shows up on every model.
It can be possible that your tablet does not come with the internal 3G modem.
There are some more networks options that shows up when you tablet has the 3G Modem.
