Yoga 3 8" 850L 850M voice calls - Thinkpad Tablet General

I bought an 850L but didn't realize voice calls are disabled, but on the 850M they're not.
Is this the only difference between the two? If so, I could switch them out.

I think so because I unknowingly ordered a 850F (grrr) and the manual that came with it says (verbatim):
The WLAN model (Lenovo YT3-850F) does not have a Micro SIM card slot.
Model Lenovo YT3-850F; Version: WLAN
Model Lenovo YT3-850L; Version: LTE
Model Lenovo YT3-850M; Version: LTE (Voice)
Wireless communication: Bluetooth 4.0; WLAN 802.11 b/g/n; GPS/GLONASS; LTE/WCDMA/GSM
PLEASE TELL ME where I can purchase an 850M!

Anyone know the call barring password for the YT3-850M? I'm trying to bar all outgoing calls. There are conflicting messages all over the internet. Some say the call barring password is device-specific, some say it's network operator-specific. I have a Truphone SIM card in it so I contacted them and of course they said to contact Lenovo. Lenovo of course says to contact the network operator. (https://support.lenovo.com/us/en/forumsolution/lp01_en!!2037816!!2041097?LinkTrack=Solr) I've tried all the obvious codes (0000, 1111, 1234, PUK, last 4 of SS, last 4 of phone #, etc.) but no luck yet.

[Q] [SM-N900V] No Service/Emergency Calls on 2g(GSM)

So a friend of mine brought a galaxy note 3 was selling cheap so I bought it because I read note 3 (verizon) were factory unlocked. I want to use a GSM sim on it, so i switched the network to gsm/umts (also tried global) but all i am getting is Emergency calls only in the notification(or barely 1 signal bar). After spending some time on it I figured out it was using 3G instead of GSM. 3G Coverage is poor where I live while GSM is excellent. but my note 3 only searches for HSPA
Changing to both, GSM/UMTS & Global had no effect. is there any way to resolve this? I only want to use GSM(2g).
(PS:nothing wrong with sim works perfect with gsm on my s3.)

SIM slot connectivity issue Zenfone 3 (ZE552KL)

Hey Guys,
Bought a new zenfone 3 (ZE552KL). Unable to receive a call on SIM slot 1 ( Micro-sd). Caller hears a "Phone is switched off" message. The same SIM however works in the nano SIM slot 2. Called my network operator and got my sim replaced but the caller still gets the same message. Performed a factory reset as suggested by Asus customer care, still no joy. Finally ordered a replacement from Asus for the zenfone 3 ( ZE552KL) and SIM slot 1 still gives me the same problem i.e. the caller getting a " phone is switched off " message.
Anyone else facing problems with the zenfone 3 in terms of sim slots related connectivity?

Haven't tried SIM 2 but certainly has no any kind of issue from SIM 1. Call and cellular data works perfectly fine. Have you checked operator vs supported frequency? And also suitable firmware for the country?

No Network on Essential phone in India

I am currently in India, and trying to use my Essential PH1 with a Vodafone India 4G sim card. The SIM is not registering with the phone, and I am unable to get any network. I keep getting the message "your SIM is not allowed to use this network". I have tried contacting the local service center, but they tell me that the handset settings need to be changed. The same SIM works well with other phones in India.
I am using a Vodafone India 4G sim.. its a 'postpaid' connection (if that matters). When I manually select the network, all the available networks are listed, when I select "choose automatically", a message pops up "already registered on the network", but i dont get any signal.
When I manually try to select Vodafone IN from the list, pop up message says "your SIM is not allowed to use this network"
I have checked with Vodafone customer care, and they are sure its a phone config issue.
The same SIM works perfectly fine in any other handset. (Currently running the same SIM in Nexus 5)
Since this phone has not been launched in India yet, there is no technical knowledge or troubleshooting database available locally. Would you be able to help me with the correct settings so that the I can continue using the phone in India?
HI
I am having the same Issue with my phone, just bought it from US. indian SIMS not registering, were you able to find a solution for this?
Thanks
No.. not yet. The Essential customer care was supposed to get back, but they are not responding since the last couple of days. Do keep in touch if you are able to find a solution...

Hi
Received an OTA today for the device, Airtel and Vodafone are now registering ,. Jio is not able to register.
Cheers
I'm having a similar problem in Japan with Softbank, which ironically bought Sprint - the sole carrier of the phone in the USA.
There is no signal at all, and when selecting Softbank manually from the list of carriers, an error message stating it can't authenticate on the network popped up.
I faced the same issue a week ago, with both Airtel and Jio not registering the device on their networks. Yesterday, I booted up the phone again, installed the OTA, and was on my way to the Airtel store to talk about it. When I put in my SIM and turned it on, it got a signal and LTE data. I didn't try the same with Jio.
The most likely reason for the phone not being detected initially is that Essential has just one SKU, as far as I know, with all IMEIs of the 99x series. That's the typical IMEI series for Verizon and Sprint in the US, which are CDMA networks. Most other GSM IMEIs are of the 35x series.
I had planned to contact Essential support about this, but I didn't get down to it. I'm not sure what exactly made it work the second time. Maybe the OTA update changed something, or maybe Airtel took a while to auto-register (whitelist) the IMEI of this phone after it first detected it being used with a legitimate Airtel SIM. Regardless, it works just fine now.
NOTE: After I was able to get a signal, I could see the LTE symbol with no internet connectivity. I changed the preferred network type to "Global" in Settings and then it worked just fine. The default setting of LTE/TDSCDMA/CDMA/EVDO/GSM/WCDMA didn't allow data, only calls and SMS.
Yes am too facing same problem with essential PH1
used all operator Indian 4g / 3g sim card
even cdma also ...no result ...no network
Product Name -Mata
Variant Openus
Baseband 2.0.c4-M1.2
Secure boot Yes
Device State Locked
anyone some clue ???
regards,
When using outside of the U.S.A change network type to Global. Secondly insert the Sim (with the phone turned off). You should receive service when you turn the device on. In case you don't, give it a moment.
I had to replace my Sim as a last resort and then it worked without a problem.
Good luck.

Voice calls not possible on Lebara network Australia

I've got a very weird issue with my Galaxy S8 (SM-G950FD)
After working fine for about 1.5 years on the network it suddenly wasn't able to make and receive calls anymore on the Lebara (Vodafone) network in Australia.
The issue spontaneously disappeared a few hours after it first surfaced but reappeared and has not gone away since.
Internet and Txt/MMS are working normally. But when someone calls me it goes straight to voicemail and when I call nothing happens for a minute or so and then it "disconnects" but no tone
When I go into the phone app and try to retrieve settings like caller ID and/or forwarding it gives the following error:
Failed to read data
Something went wrong. Check your
Sim Card or network connection,
then try again
When I insert the sim into an S7 it's working. When I insert the sim from the S7 into the S8 (Optus network) the S8 works as well.
I've performed a factory reset (without restoring the settings)
I've gotten a new sim and Lebara has ported the number to it but that didn't help
Being a dual sim I've tried using the shared sd/sim slot but same issue.. data/mms/txt working no voice.
I've tried copying the apn settings the S7 displays with the Lebara sim to the S8 but that didn't help either.
I've now used Odin to flash the phone back to the Oreo version with the December 2018 security update and that didn't help either.
Any other ideas?
Thanks
I've managed to narrow down the issue a bit.
Also went out to purchase a Vodafone Pre-paid sim. That one didn't work either at first but after some troubleshooting with support of Vodafone we've found out that the S8 doesn't connect to the 3G network of Vodafone Australia.
When I have the SIM of another provider in there and limited the network mode to 2G/3G autoconnect the phone just finds the 2 other networks on 3G (AFAIK 2G has been phased out).
I've tried to get into the advanced service mode but this doesn't seem to be possible anymore.
Is there a way to try to see which bands are active on the S8 and better yet enable them all?
