phone not reachable while using gprs

Whenever I connect my jasjar to gprs anyone trying to call me gets a "User not reachable" message.
I contacted my service provider and they told me that this is because all the four incoming ports are busy in data transfer that is why a user not reachable message is played.
This is a very big problem for me as I m connected to net most of the times and also dont want to miss any calls
Hoping someone has a solution.........

I had the same problem the other day on my XDA IIi, family trying to call and not getting through but i was playing around a lot on the web. I nearly always have my GPRS connected and usually don't have any problem receiving calls, must be just because i was downloading at the time.

Hey, there is a registry hack in the wiki about keeping gprs open all then time. Would there be another possible to keep one channel open for gsm all the time ??
regards,
Ruud

unfortunatly, this is the radio design or limitations of most gsm radios. It uses a radio that can only have GPRS active or Voice active. If you can use utms, you can have both utms and voice active.
It is only an issue when data is actually active (downloading or surfing) . Its ok if gprs is connected, only problem is when it is actually transmitting or receiving...

there is currently no utms network available at my place right now
Is there any way to keep one of the ports free for recieving voice calls only while others can take gprs data

Hi Pankaj bhai,
Assuming the signal strength is good...U will receive a call while u are surfing the net...but not when downloading any file...I use "GPRS Always ON" and I do not face any problems receving the calls.

Are you Airtel? I had this problem - when I was in Delhi - Had to call and ask them for FULL service.
Seems that they have partial GPRS and full GPRS.
Class 2 ( ithink this is what it is called) means that data call will be dropped when voice comes in - so if you are doing anything on web/dl - it should stop to give way for voice - which is not happening in your case.
I love UMTS - you can do both - my emails keep on arriving even when i am talking on phone.

ya nitin i m on airtel
I had complained to them regarding this bt they said this is a limitation with gprs technology and presently there is no solution
I dont have a prob while i m connected bt i dont recieve calls when downloading data.
by the way which umts u r using

No - the way GPRS is designed, data is bumped off when you get voice call. Those people at Airtel didnot know anything - so you have to keep on pressing. It was more than 1 year back in Delhi. Its called class 10 service (I think - not class b or c as i wrote earlier). That time there were 2 kinds of GPRS - 150rs (which they advertised and was crippled) and a hidden 499rs one. Its all about the number of channels used (sorry - I have not updated myself on 2.5G)
In short - you got to ask them - getting engage tone when you are using data is not service - Airtel is not giving you proper service. Ask softly first - then rudely (thats the only way they listen)
I am in Dubai - using Etisalat UMTS.

I am too with Airtel and that 150 Rs unlimited..using since 2002...In all these days with various cell phones...I found that receiving a call depends on the GPRS signal strength..if it is good...i still can receive tha call..I hv been able to receive a call while d/l from web.
Nitin is right people at Airtel are usless(Gadhe hai sale)

thanx 4 help guys
I now know what to ask for
probably i ll b able to get the full service now
But guys u r damn rite most of the ppl at airtel r idiots they r nt taught anything except talking blah blah
thats wht i love bout this forum nice helpfull ppl everywhere

[Q] Sim Unlock

Is there a way to free sim unlock my HTC Wildfire?

Mabye
Well my brother has a ZTE Racer and found a website via google that makes your phone sim free for free (lol) but i dunno if theres a site like it for htc mobiles

HTC wildfire
Hope someone can help!
I got my brother in law htc wildfire.
And got a code to open it up to any network.
We got the code from an internet site called GSMliberty, the code has worked to a degree.
It receives calls and can make them, the time is right, and the internet works over wi-fi of course.
But it will not connect to the internet on its own ie 3g.
The phone was locked to 3 and I have tried 2 different sim cards in, orange and t-mobile, both have unlimited data plans.
I have changed the apn setting to match each network/carrier and all I get is connection failed.
I have called and emailed the code people who say it is down to the data set up.
I have been in touch with t-mobile his the network/carrier he wants and they have talked us through it, as have htc help centre but to no avail.
However if we put a 3 sim back in, it connects to the internet, swap it back and change the internet setting to the network required and won't work.
Does anyone have any ideas or help?
It has not been rooted or messed with, just the unlock code.
Kindest regards
Shaun

Stock Rom Carrier Unlocked not able to receive/send calls but can use data and SMS

Hey,
So I bought an LG G4 from Vodafone UK and unlocked it so i could use my Three sim card.
Weird thing is I can use Mobile Data and send/receive SMS if I am on 4G. The person who is calling me can hear the calling tone as if they were calling someone but I don't actually receive the call.
When I switch to 2G/3G it simply does not connect to the network.
I have done a factory reset and it did not fix the problem.
Any ideas?
Thanks
tl;dr : can't send/receive calls but can use data and send/receive sms (through 4G only)

Maybe you need to register your IMEI on the network? That's what I had to for At&t.

How would you go about doing that? Apart from manually searching for networks (I can see other carriers like O2, vodafone, EE, but I can't see my carrier Three ; the person living in the flat with me is on Three as well and they have no problem, so it's not a coverage issue. I have bought the phone from vodafone, unlocked it and trying to use it with Three).
Do I have to call Three for this IMEI registration or..?
Thanks

Best bet will be calling your service prover and have them register it. I had to call At&t and have them register my IMEI since I couldn't use internet or make calls.

Just had a long chat over the phone with them and in the end he said the 'engineers' found a 'problem' on their end and it should be fixed in @5 days. He didn't want to mention what problem or how / why it happened. Oh well fingers crossed.
Thanks!

update : so after about 4 calls with customer service (across 3 weeks) and 2 trips to the 'Three' store i'm basically stuck and would need your help guys.
backstory : I've contacted them once at the start of January and they said they found the issue and they will fix it by 7th of January which didn't Happen. On 7th of January they said they are sorry and it will be fixed by 14th of January which didn't happen either. After that I received a message that the problem was fixed and if i had any other issues I should contact them, which I did because the problem was not solved. Yesterday I went to the shop again and the 'tech' guy told me that it should be working and he gave me a new sim card just to be sure, and if that didn't work he said call customer support and ask for contract cancellation. Today I got called by customer service and I have told them that it still doesn't work and I'm paying for something I can't use and I've been told to request contract cancellation which they didn't believe and said I have to pay the rest of the contract length in order to cancel, which is absurd. I went again to the shop and the new customer service person that was assigned to me said they don't have any tech people and she seemed she didn't believe when i said i talked to one the day before. She tested the sim on their phones and it worked and also she took my phone "in the back (strange cause she said they don't have any tech)" and said I had my phone set to 2G (which I didn't, it was set to 2G/3G) and that that was the problem. strangely, for that split moment i had one bar for 3g and the call went through. Straight after that phone stopped working (it was just that small area in which it worked). I told her that that's not the problem and she's like "welp you didn't make your contract at the store, you made it online so I can't help you , you have to call customer service". So I'm basically stuck with a contract which I can't use and I have no idea what to do.
problem : I cannot register to the Three network (only in small random areas, few of them) but I have no problems with other SIM cards from other Carriers (Orange, EE, Vodafone, O2). I have bought the phone from vodafone and unlocked it and last time customer service told me they can't give support to phones that were not bought from their store. So I'm stuck here with a phone contract which I can not use to make or receive calls, but I can use the mobile data and send receive texts. I am considering rooting it and puting a custom ROM , although I'm not sure if that would fix the problems (maybe issues with certain bandwiths?.
Any help or ideas much appreciated!

Same problem here
Hi all. Same problem here but different issue.
Origin : G4 buy used on November. IMEI fully working and not blacklisted (calling my french phone provider this morning, it tell me that's IMEI is ok and phone not stollen and it try to repair remotly my carrier but didn't work)
Problem : Fully working since i picked up a call and answer ... and then when the call is finish i tried to call someone 10 minutes after and totally loose signal(connection) (Orange/Sosh)
What i've maid before : Playing a lot @ a boring but adictive game. High temperature since 3 days because i play a lot but temperature decrease when i stop playing.
I've used a legal app to record a patern and make some actions without my intervention (RepetiTouch Free (root)) to make races in the game.
That's all ! No drop, no hit, nothing ! Just playing, having a call, hang off and then want to make an other call and nothing.
Since the last 6 hours : Signal ok - Data ok (can go on internet / GAPPS etc..) - CAN receive and send SMS (i've don't trie MMS) !!! but .... can't receive and can't send any call.
I was on Genesys 3.5 and i've update to 3.7 when i see the problem, believing that's it will fixe the issue but ... no ....
Formating and going to stock ROM but with root SU etc..... Can't receive and send call too ....
I'm going to back to stock with KDZ .... but i really believe that's it will not work .....
AND .... to finish and kill my joy .... i've unlock bootloader with LG tools since 2 month .....so my phone is no longer under warranty.
My SIM card work on others phones ... other sim cards didn't work in my phone ....
If anyone have this issue ... please tell us

Sorry bro cant help you here. Never heard of that problem before but my idea is that you should refund that phone back to Vodafone UK.

RN5 AI Dual Camera Global Very slow network speed on mobile data in europe!

Guys , I just bought the Redmi Note 5 AI Dual Camera phone 4/64 gb variant. It came in vacum , original package and everything works fine. But after all the updates and everything done , after an day I bought the daily mobile internet package. It contains 100 MB of data u can use in 24h. Sadly it's 3G network and we cant get decent speed , but on my phone the speed is in bytes literaly. I can only send messages in facebook messenger as it displays online status. I cant use facebook, instagram or the browser. The phone keeps refreshing and the speed stays the same , mostly 0.50 K/s up to 5.00 K/s, nothing more.I live in Bosnia if that maters. Could that be issue with my provider or is it with the phone cause its chinesse and it isnt compactible or something like that ? Help me please..

Absolutely network problem with your service provider. . Try to use proper APN settings

Luckily it was exactly that, somehow the phone didnt get right APN , the default one wasnt working. So I called service and they provided me with a new APN and they activated something and after reset the phone , then finally the speed was much better.
