[Q] Cannot read USSD messages

hello,
1st, sorry to bother with a new thread (as per the video)
2nd, i have just got an Acer neotouch S200, i like it, but i have two problems so far. (i live in Cairo, Egypt, and this phone uses the Etisalat network)
1) i cant read the service messages that are sent from my service provider (it sends me cost details of calls, remaining balance..etc), and it is currently displayed as a USSD type with the same notification every time " USSD Transmission Ended ".
i found a USSD type changer in the settings, but it has only 4 versions, none of them worked, i tried
is there a way to read these messages normally?
2) is there a way to switch last name/first name in the phone book? because it displays last name 1st, and we do not use that system here in Egypt.
the system currently used is EN-AR 1.003d
the CPU is a QUALCOMM, type QSD8250
thank you in advance for your time, hopefully i`ll get an answer..

An LG G Pro 2 D838 in Egypt !!! Problems

I bought the D838 from Emirates 2 weeks aga , and use it in Cairo/Egypt. I have the following 2 issues:
1- Not bale to make Video call , and always receive the message :" When in Roaming, no video call is possible" . I have checked with Vodafone support in Cairo and made sure that Global roaming is off, but still get the same message.
2- can not receive or send MMS. it always fails.
3- There is a software update on the phone, and every time I try to update, I get error after few seconds.
To me it seems that the ROM is only for Korea, so the phone , when using Vodafone Egypt, thinks he thinks am using a Korean SIM in Cairo, so there is roaming. I can not find any other reason. Except those 3 issues, I am using the phone for calls, sms, emails, Facebook, whatsapp,...
Can some one advise ? is there a ROM that I can download safely to overcome this ?
LG support in Cairo, said they only support LG G Pro and nit Pro 2.
Thank you all in advance

XZs on O2 UK "Invalid number" making calls

Hi
I just bought an XZs dual SIM version. I'm having a very strange issue with it.
I have two SIMs installed: one on O2 UK and the other on Three UK.
The three chip works perfectly. Can do everything, voice, data, SMS etc... all good.
The O2 chip however has a strange issue. Every phone call I make it says "Invalid number".
Even if I call using the international +XX XXXXXX type or if I call using the UK style 07XXXXX both say "Invalid number" and do not complete the call.
What is odd is that I can receive incoming calls to the number. SMS and data also works, just making outgoing calls fails.
I checked that the phone supports the bands that O2 uses and it does. It does connect to the network (as I said I can receive calls, use data, send and receive SMS but just cannot make any outgoing calls)
The phone came from Hong Kong, and both O2 and Sony have flat out refused to help because I didn't buy the phone in the UK.
But well, it's a mobile phone, it should work in my country even if it's from HK.
I cannot really understand why I can receive calls but not make them. The SIM card works in my UK Samsung S6 so I do not think it's a network issue.
I have tried setting it to GSM only as it is my work phone and I really only need it for making calls. I've tried WCDMA / 4G / 3G but nothing fixes it.
I have reset the phone. Checked carrier settings etc.
Lastly I have tried swapping the chips around, and tried it with just one SIM but still the problem occurs.
Please can anyone give any suggestions on resolving this issue before I have to send it back ?
Thanks!

never mind. i solved it.
it was a provisioning error by the network, contacted O2 today and they resolved it by doing some kind of reset their end, which they didn't want to elaborate on.
fixed now.

Not able to receive calls and send calls. But able to send text and used data

My LG G Pro 2 is a Taiwan version and has the latest Lollipop update. Its the stock rom and not rooted. The phone has the issue above where it can't call or receive calls but it can receive text messages and use 4G data. When looking at the sim the phone says Call settings unavalible...
I have tested the sim with the LG G4 and it is fine. Any idea how to fix?

1. Both Sim card have network and data enable and bills are paid ..everything working fine.
2.i can make call on both sim
3. i can receive call on both Sim
4.Both Card cannot send SMS ... but working fine sending MMS.
Since the beginning, I have in mind that my issue came from a ''hidden settings'' from the phone that might not be set properly because SMS was working fine in the first 2-3 days of owning this device.
Both sim card work good when I put them on my Old Asus Zenfone 3 Zoom. I can send SMS from the Zenfone.
My device is Vivo Iqoo Neo 855 (Model: V1936A) Firmware version # PD1936C_A_1.5.39 (Monster UI / Funtouch OS 9)

You have the same issue ?
Whats is your Device ?

check your SMSC be sure that it is correct.if so than u should preform FACTORY RESET SETTING (without losing ur deta of course)

Finally I've called my carrier and they Reset my profil. That's fixed my issue for few days. Afterward, it's coma back so called my carrier a second time, reset my profil again and than I change SMS app by default and this issue never came back for 3 month.
So basicly, in my mind, the default sms app of this Vivo Iqoo messed up with my carrier profil.
