[Q] SM-T211 (GSM) - How to - SIM?

Hello!
I have plugged the sim card into my tablet but as far as I can see it doesn't even recognize it ?
Phone is bought at the same carrier where I got that mini sim?
Do I need somehow to activate that port or what?
Thanks

Hi,
my Tab 3 8.0 lte didn't need any sim activaton.
I just put in the sim and when the tab was powerd on, it asked for pin code.
Is it possible the card is uppside down?

Sorry for late response. It was my fault.
SIM card is new, and It's not asking for PIN by default, and it wasnt registering on the network because no network profile was SELECTED.
I had profiles, but they didnt had DOT on the right side (they didnt had selection dot).
Now everything is perfect

:good: I'm glad You got it working...

[Q] Just bought a used T-Mobile Note 10.1 2014

As the title says, I've been dying to get a Note 10.1. I finally got one but it happens to be a T-Mobile version and the sim card has been removed. I don't plan on getting 4G service ever if I can avoid it.
So now I have a few questions:
1. Will I be able to get updates like the wifi only tablets do or will I be forced to get T-Mobile service when updates come out?
2. I have these annoying notifications about the missing sim card. Is there a way around this? I have Sprint service for my phones so I really don't know much about sim cards. Do I need to go to T-Mobile and just ask for one to pop in without getting service? Are they free or would they send me packing because I don't have their service?
3. I also have the x'd out signal meter that I would love to get rid of.
Any advice you guys can give me as a sim card/carrier tablet noob would be very helpful.

- You can get updates with WiFi only in fact some updates requires a WiFi connection in order to download since all data plans are limited on tablets

- You can get a SIM card for about $10, however you don't need to have service with T-Mobile you can put the SIM card and whenever you are not connected to WiFi but you get LTE service it would send you to a page where you can add a data package but thats completely optional
I also have the x'd out signal meter that I would love to get rid of.

Once you put a SIM card it would go away maybe there is a Xposed module that can remove the signal meter and the No SIM card notifcation

Thank you very much. Good info.

Why not root and flash a rom that doesn't have those things enabled.
Flashing a wifi version of a rom might do the trick.
I've done the reverse and flashed a 4G rom to my Wifi only device and simpy disable the phone and sms apps. Sometimes you have to be careful but I haven't had an issue both ways.

[Q] Enable Mobile Hotspot on Unlocked ATT Galaxy Note 2

We have a Galaxy Note 2 from ATT now. Just upgraded, so we're not using it. We want to take it to Europe to use as a phone and a hotspot for our computers on our trip. I've read that people do that with unlocked Androids and a European SIM.
I was able to unlock the phone with no problem using a data only T-Mobile SIM card in the process. The problem is that I can't turn the Mobile Hot Spot on. I've tried with the valid data only T-mobild SIM installed. When I try to turn the hotspot on, it says that either the network is not available, or there's an invalid SIM. I'm worried that it's the ATT restrictions on the phone that aren't going away even if the phone is unlocked, and there's a different SIM in place.
Does anyone know what we have to do to enable the hotspot, so that this phone can be used in Europe?
Thanks.

Try with wifix.apk

Thanks. That looks like a good app to fix problems connecting to external wifi sources. However, I want my phone to BE the wifi source when in Europe. Still looking for a solution.

The thing that sticks out to me is that you actually need the correct Sim card that is provisioned for phone service.. I'm assuming this "data only sim" was provisioned for a tablet and therefore can't make any calls... the network unavailable message will show up even with no Sim installed and trying to enable a hotspot. You need a valid cell service in order to hotspot.

Hope Getting the Right SIM will do it.

Thanks. I hope that's what the problem is. It would make things simpler to be sure. I just didn't want to get there and then find out it wasn't going to work. In the meantime, I found my old Galaxy S 3. I managed to unlock it, root it, and install basic ROM. Thought maybe that would work, as well. I'll know by next week.

sim 2 mobile data not connecting

I am using mi max 128 GB. mobile data is not connecting with sim 2. With sim 1 it's connecting fine. I tried to connect only 2g also but no use. I had verified the sim with other phone and it's working fine. Both my sims are BSNL and both have working data plans. I tried removing and reinserting sim, rebooting, tinkering with *#*#4636#*#* but nothing worked. To be precise nano sim is working for data connection but micro sim slot i.e sim 2 slot sim is not working for data connection but working fine for calls and messages. Please tell me what to do?

It's a stock MIUI 8.2. The OTA update from 8.1 to 8.2 came just now and i updated. Even after update same problem is there. I had also tried with AIRTEL sim. But the data is not connecting.

I´m not on Miui to test it, but if you got to Settings -> Sim Cards you can click on Sim-Card 2 and there are some settings like prefered Sim Card Settings or something like that.There you can choose something like for data connection
I bet you've already tried that, haven't you?

Yes that is the procedure to change the data connection from one sim to other sim. Do I have to go to service center?

I can´t give you an answer for that. I´m in Germany and here is no Xiaomi Support for their Devices. If I was you, I would flash another Rom and test it, but if you have a normal warranty you can go to the next service center and let check it by Xiaomi.

Two Sim Cards from the same network will not work. Try using a different network sim card in slot 2 and check if it works. When you use two simcards from the same network, are you able to call using sim2?

can you not select it from the bottom menu i can switch sim one or 2 but cannot use both at once

From how much time you are facing this issue?
Is it appeared randomly?
Or it happened after doing something?

i had a similar problem. after a software update was applied automatically, I lost wifi calling b/c my inserted SIM is not tmobile despite the device being unlocked. So, I inserted a tmobile sim and used ODIN to flash the latest stock firmware, and then i got wifi calling back. I'd test it first with a Tmobile sim (i bought one off ebay) and then restart the device. If that doesn't fix it, you may have to reflash stock firmware like I did.

I have a T-Mobile SIM installed right now, I've shut it off and restarted numerous times. I've never used ODIN nor flashed firmware. Where would I get the correct software to do this? Also, would it make a difference if my phone is an international dual SIM?

Software and instructions are here on xda in our device forum thread.
I'm unsure about your device. Dual sim intl version is definitely a different beast. You may want to ask in that forum... Sorry.

I had a similar problem and couldn't even find the wi-fi calling option, let alone enable it. Here's how I fixed it: I enabled Bixby and updated it. Then I said "Hey Bixby, enable wi-fi calling..." and not only did Bixby enable it, she located the settings. The setting lives under "Call Settings" which isn't accessible in any other way than by using Bixby (at least from what I can see).
Now wi-fi calling is enabled and I now have a whole host of additional call settings available to me.
Hope this helps.

I'm using a TMobile SIM on the TMobile network. The settings are stock Android (not TMobile) but they can only be accessed by using Bixby. They aren't found by browsing Settings or searching the phone.
I've made several successful WiFi calls since
