Hi folks, can anyone please help me with this problem?
My brother in law has asked me to look at his S740. He has tried several o2 SIM cards (UK) in this phone but always gets told there is no signal.
Not only that, but there is a symbol where the strength meter should be that isn't documented in the user guide.
He has also tried my o2 (3G) sim and a Vodafone sim, both UK.
Any advice gratefully recieved. We have tried several hard resets also.
Thanks
This means it's looking for signal. My guess: Still SIM-locked?

Not sure if it's SIM locked as there is a menu to select which carrier to use.
It reads the SIM correctly and sets it all up for o2, but just doesnt get any signal.
Does anyone know where the GSM antenna is on these? Maybe its a bad connection.
UPDATE:
I've had a mail back from HTC that recommends I send it in for repair, lol.
Now do I take it they are robbing buggers or do I take it that the icon is an indicator of a hardware fault??
Hmmmm, dilemma. lol
Are there any more suggestions on what it may be?
Has anyone successfully taken one of these apart?
it may be because of a hardware error...try to connect to a wifi network...if it impossible to find a wifi network then it is due to a harware problem.Most likely because the FR coaxial cable is out of its possision...download the service manual and see how to fix it.

Hi sasiskas, it conects fine to my wireless network at home. I take it from your response that the cable serves a double purpose.
I downloaded the service manual so I could take a look, but only got as far as removing the 4 screws at the back. lol, I couldn't figure out how to get it off, lol
I'm still stuck at the assumption that it is indeed SIM locked, and so will try to find a suitable card to try out.

Try contacting with your phone's provider (shop,e-bay seller whoever it is) and ask him details about the sim.Good luck.

Thanks. I have tried the same but just keep getting a vender ID, (lol spelling), error.
I would appreciate any input whether you have success or not, it just may spark an idea off.
I cant get in touch with any sales or provider as it was gifted to my bro in law. He's not that bothered about it but would like to have it working if he can.
Thanks folks.
Hey! I think I know the solution to your problem...I had exactly the same problem when I hardReseted my phone.
Go to "Start-settings-Phone-Band Select"
and then select
1.Network type : Auto
2.Band Type : "Euro" if you live in Europe, "US" if you live in USA , or "Japan" if you live in Japan.
Good luck...Let us know if it worked!

Yes that is a good suggestion because the phone will display that icon if it can't find a *usable* network, be it that the SIM doesn't allow it or if the bands don't match the selection on the phone or the bands are not usable by the phone hardware etc.
I would suggest downloading & running HTC Field Test (fieldtest.exe) with & without a SIM installed, with each network & band setting & see if it shows any towers or signal. (Normally you want Auto for both but you may not have that option or you might prefer to set to a KNOWN working band to conserve battery & minimize searching) If should show something even without SIM or with SIM lock because it's supposed to support emergency calls either way. If it shows signals with SIM but you still have same no service icon then it's likely SIM locked (although the phone should alert you to that fact) so odds are the phone hardware, rom or settings do not support whatever signals are available to you. (Btw if field test shows N/A for all the values you need to app unlock your phone)
Hope that helps.
Bill
can you share a link with HTC Field Test?Thnx
Search is your friend.

Hey all I'm having a very similar problem.
Had my HTC for some months now but in the past few days I've found that my network signal is becoming very unpredictable.
I'm also on O2 and I used to have a pretty contstant H (I presume HSDPA) connection.
Howeever im finding now the phone with go from H to 3G to GPRS to E to no signal in the course of 5 mines and round and round again!
Its very annoying as it means I cant make / received calls or texts fluently and even cut me off on a phone call too.
However usually on phone calls it will keep me connected ok till I hang up and then go to no signal.
I've checked the wireless and it is picking up networks..
Any other suggestions? I will try the field test tomorrow...
PS I know its not the network as my work blackberry is O2 and is not having this issue..
Cheers in advance!
Well, just to close my input on this thread.
I tried various ROM's available from this site and none worked.
I did try the band selection settings but still a no go.
I did have limited success but overall, nothing. The phone has now gone back to the person who asked me to look into it and to my knowledge he is going to sell it to one of these phone reclaim companies.
I did check and one place, I think through the post office, is offering £80 ish so not bad I suppose.
Anyway, thank you to all who have made suggestions and wotnot. Personally I'm still happy with an old Nokia 6300 and my Wizard (Mini-S)
Thanks folks.
Hi peeps I need some help over here. Currently my phone is unable to connect to the my network. It shows "No Service" yet I am able to detect networks. Just that I am unable to connect to them. The sim card that I used is working on other phone which shows full reception. To confirm that my HTC Hero has problem, I used another working sim card on it. Nothing has changed though. I am not sure if it is a hardware or firmware problem.
I am using a rooted phone flashed with Elinux Special Edition 2.2.1 Final, Baseband version 63.18.55.06PU_6.35.15.14
Sounds like the imei is blacklisted. Can't do much with that
Sent from my Motorola Startac running Android 3.0 Honeycomb.
How do I check if imei is black listed? I bought this phone first hand.
In fact I had sent to htc for servicing and they told me its the faulty hardware. My phone warranty expired 2 months ago Now they want to charge my an insane price to change the whole phone board Is there anyware to fix this phone because I actually intended to sell this off in 2 months time.
Is your phone locked to a different supplier? Did it used to work with this SIM?

It was working fine that day. The next morning there is no reception as shown in the phone.
Who's your network provider ?
I've had no end of grief with meteor IE, every other sim works fine but meteor only gets a service if you turn off 3g

Hi, I have been looking everywhere for answers and hopefully some one here can give me one.
I researched rugged phones and decided on the BV7000 Pro because it supports LTE Bands 1/3/7/8/20
My cell provider - Virgin Mobile Canada stated they run on LTE Bands 2/3/4/7
So my phone should work on Bands 3/7
When the phone searches for networks, it is able to display Virgin 4G, Telus 4G, EXT 2G, EXT 4G
When I try to connect to Virgin 4G, it tries then states it failed to register to the network and to try again later
I have confirmed my SIM card and APN settings with Virgin and the SIM card works in my old Motorola Razr but on 3G. The BV7000 doesn't work on the 3G bands Virgin uses so I can't try connecting using 3G.
So I want to know what you think is the reason why my phone can't register to Virgin Mobile Canada's Network?
Other BV7000 Users in Canada, United States and Mexico have reported the same problem.
I have contacted Blackview support and they eventually stated it won't work in Canada but provided no reason why. They posted this 11 days after I had purchased the phone and it was in the middle of being sent to me. However I suspect their support isn't the brightest based on some of the responses I have seen on their forum. The BV6000 works in Canada and the US.
I don't know anything about how the phone communicates to the provider exactly but to me it seems like there is a failure in communication in terms of security which is preventing it from connecting.
Hopefully some one can shed some light on this and maybe find a way around it so I can get this thing to work as a phone.
bv7000 pro, fails on mexico
hello, i have the same problem, live in mexico, it doesnt support 4g, If i have luck it will be 3g data, but i never seen that, only edge, i have i cool phone, but It is useless on internet data.
On the blackview forum theres no help there, Only users complaining about the same in North America

Hi, I unfortunately haven't found a solution yet. I have attempted to request a return through the AliExpress website and the seller has completely ignored me. I had to contact AliExpress customer support to have my return request escalated. The seller finally contacted me today asking if I had received the phone. Which is a stupid question because there clearly is communication between use showing I received the phone and have had problems with it.
Your only option is to try to return it or find a phone provider there that it will work on so you can try to sell it to some one on that network or switch to that provider. I found a provider in Canada called 'Rogers' that it works on but I can't switch to them because I would loose my old plan that is cheaper than the modern equivalent.
Either that or learn how to hack the phone to get to the modem that technically can operate on all bands, they just have to be enabled. Blackview uses the MediaTek CPU. I am desperate to try but I am pretty sure I would kill the phone.
sooo...... do you kill the phone??.. hahaha
Is a bad phone, i try with another company in mexico (telcel), but it lost a lot the signal, when you have to make a call, surprise you can't.
asking on the facebook pago of blackview, they say is a hardware problem, so, there is no solution, only keep waiting for bv8000 (if you want to try again)

Still waiting for either the aliexpress customer care to figure it out or the seller to reply to me. I haven't done anything with the phone yet. I have been trying to sell it locally but only one person was interested.
When you say they said there is a hardware problem, do you mean the phone is defective or the hardware just isn't configured to work with North American networks but works fine in Asia?

i understand that..... is work fine in asia but not in north america.
i'm in contact whit my seller, they try to help me with 3 problems,
- Does not detect my company's signal
- Only works with edge (doesn't support 3g or 4g)
- after make or receive a call, i can't do another one, have to reboot the device.

Hi, I was just wondering what website you bought your phone through? I bought mine through the AliExpress website, through the Desoon Technology Co., Limited store. The seller has ignored my repeated requests for a return for refund and AliExpress Customer Service won't even talk to me anymore. Nice place to run a shady store when the host website can't even enforce their own rules.
i bought on ebay, honesty i thought i will find a solution for the problem #3 (reboot after a call), but nope, blackview forum is very slow on don't give any solution.
for the problema 1 and 2.... there is no solution, the phone doesn't support 3g whit most of the companys in America (canada, us, mexico or south america), is hardware problem., this problem is fixed on the new bv8000 pro, is has more frequency bands to support global network.
It does not work 3G or 4G only 2G.
I have a blackView bv7000 pro, but it does not detect the networks of 3G or 4G only 2G, here works well only the phone with 2 SIM, the wathapp works well only the internet is very slow, in one word is not good for the internet, it is fast with the applications, but with the internet nothing else is not good.
This in Mexico with any telephone service here.
Hi everyone
I am in the UK and bought the Note 4 Global version, as in the UK my provider uses Band 20
I am on Tesco, which piggy-backs the O2 network
However, on inserting the sim I receive the No Network error.
Tesco give me the usual "we don't sell those handsets so we can't provide technical support blah blah" "It must be locked blah blah"
The sim is fine as it was in his iPhone 5 (and still is because this won't connect to Tesco)
The Mobile Networks setting has been changed to what was on the previous phone, but with no joy.
Any ideas anyone?
Thanks in advance
Edit for stupidity:
Android 7.0 NRD90M
MIUI ver 9.0.5.0
Have you tried any other sim card in the phone? You can get one of those cheapie PAYG sims (for example, EE) from Tesco or your corner shop and see whether it has the same problem (which might point to a hardware issue or something funny going on with your ROM). I am not sure why you would have had to change the mobile networks setting. That should not be necessary at all.

Forgot to mention this is my son's phone.
I have an EE pay monthly sim. Tried that. Same thing. No Network.
Irony in the fact that it says TESCO 4G in the top band by the clock when he puts his sim in the Note 4 and 2 bars on connection.

Ok, it definitely should work with EE, and so this is clearly not a Tesco mobile problem. Either the hardware is faulty or the ROM (particularly the modem drivers) is faulty. You might want to return the phone.

It looks like the same issue (on a different Xiaomi phone). The solution is probably the same - flashing the appropriate modem (firmware) files, or flashing a new complete ROM. I wasn't sure you wanted to go down that route, as it would give the vendor an escape route if something goes awry, or if the process doesn't solve the problem.

If the phone sees the signal and it does detect 4g ,than the phone is ok.
The problem is that 110db . That's practically dead zone. I would say your location is the problem. I know you said that Samsung has 2 bars but this is crappy phone .
Just to be sure, can you check in a a place with strong 4g signal?

Believe it or not, Tesco has really strong 4G in my village. Never a problem on that carrier
EE however is ****. I have "H" on their network and -123 dBm

My main problem lies with the calls and texts not being able to be connected

It seems that you will have to go down that route, unless you return the phone. Whether it works or not will depend on whether it is a hardware problem or just a ROM/firmware problem.
By the way, there is a firmware repository here: https://forum.xda-developers.com/showpost.php?p=73534612&postcount=89
This requires you to have TWRP recovery.

See if they want me to send it back or give permission to add the modem drivers with warranty intact
Just noticed that with WIFI on it says I have Tesco 4G. When I turn WIFI off I have no service.
Bizarrely, after reading, this has been going on since the Note 3
Strangely, the phone is giving 4 bars for connectivity for calls. Yet you just try and a make a call

These things are often a hit-and-miss affair, especially when buying from outside the EU. I bought mine (two) from eBay (UK and Ireland based sellers) - much easier to get refunds via PayPal (and more likely to get a proper Global ROM). But it is possible that your problem will be fixed by flashing the latest global stable ROM.
Update
Took it to the Tesco Phone Shop this morning and they couldn't get any of their settings to work. Consistently No Network. Wouldn't even connect to the Tesco guy's Vodafone sim.
Tried a Virgin sim and it wouldn't connect either
Guessing something wrong with the global rom now?
As with Note 3, MIUI 8 and the missing modem drivers?
Sparked an email back to Geekbuying to see what they can do
Thanks all

Possibly - but there is also a possibility that it is a hardware problem. That will only become clear after successfully flashing a complete ROM (global or otherwise). Whether the ROM is global or China should not have any effect on connecting to a phone network (especially EE).
Which version of MIUI are you on? Try updating of there is an update available and see if that helps.
Hello,
My Elderly grandad has just moved rural in the UK and needs to use wifi calling as there is no mobile signal, he has an old Samsung S6 which he uses which my brother bought off ebay.
The issues is the S6 is an AT&T version and for whatever reason the wifi calling setting will not turn on, on contacting Samsung they say this is likely due to the fact its an AT&T version of the phone and there is compatability issue. His carrier 3 ( the phone is unlocked) allows wifi calling so it's definitely a phone issue.
I wondered if I could flash a different firmware or such as it's a software issue and get it working?
Any help would be awesome, otherwise the phone is now useless.
Thanks!
