Selling hero for £150

I am thinking of selling my hero for round £150 because i can just not sort out the problem it has so maybe some1 with abit more knowledge will be able to sort it. It all works fine apart from the problem with the sim card which is for some reason it does not register any sim cards. The phone is unlocked and i was using a 3 sim card in for about 2 months but then all of a sudden i lost connection and then i could not reconnect with any sim card =/ i have tried different firmwares and radios but nothing seems to help. It certainly isn't barred i know that so i really duno what is up with it but would be a bargin for someone who does know. P/M if your interested
It ssems like phone has been blocked.Did you buy it from previous user? Contact him/her , or the branded supplier with imei number for their explanation.
no it use to be on contract but had a problem and came off but it hadn't been blocked by them i was using it for a while after i had come off use to work fine then it just did this. I have heard there are problems with 3 sim cards sometimes thow so wondering if it was the sim cause other sims just get stuck on the registering bit like the sim unlock hasn't worked
Just curious, but why haven't you contacted whoever you bought the phone off?
Definitely sounds to me like the handset has been barred. If you bought it as part of a contract, but then cancelled the contract early, well it makes sense for the operator to bar the handset if you didn't send it back.
Quick call to 3 (assuming that's who you bought it from) should give you an answer.
no its a tmobile i shall ring them tomorrow see what they say
Wavesecure in ROM, allowing to lock / locate / wipe your device remotely in the event of loss and be notified if the SIM is changed.
that doesn't really solve none working sims though does it ?
iv just paid for an imei check and just waiting for the result now
this phone is blocked by tmobile but not by other networks that is why it registers on tmobile but wont make calls or texts so am wondering if its something to do with the unlock code iv put in =/

Can't send or receive calls, please help.

Last night I tried to send an SMS, but it wouldn't go, so tried to make a call and it just wouldn't!
So I tried to call me number only to get the message "Calls are not currently being connected to this number". If I turn my off and try to call it it goes to voice mail etc.
I have tried a factory reset, but its still not working. it thinks it has a network, and my internet works on the phone. also, the SIM works fine in another phone...
anyone got any suggestions, I'm going away over Christmas and really need my phone to be working.
If the network is refusing to connect to that particular handset it suggests something a little more sinister.
Just to confirm, SIM in DHD does not work, no sms, no calls. SIM in another handset works fine.
If this is the case, then your DHD may have been IMEI network blocked, i.e. reported lost or stolen. Did you buy the DHD from new?
For a small fee you can check to see if your DHD has been reported lost or stolen > CheckMEND
That's right, SIM doesn't work in DHD for SMS's and Calls, but does in my other phone, but HSDPA does work.
the phone came directly from T-Mobile, I called them but they we're very unhelpful, didn't ask anything or check any thing, just suggested sending it away for repair!
I'd get it replaced. Sounds very odd. Have you tried another SIM card in it? Its probably SIM locked, so you'd need to sort that out before you can try.
Just to fill you all in, I eventually got this sorted! only took three weeks!!!!!
What happened was, the phone T-Mobile sent me doesn't match the box and paperwork it came with, the IMEI and Serial numbers are different.
It now transpires that the idiot who has the matching phone/paperwork/box etc. lost their phone and reported it stolen, so when he gave them the phone details, he (or she) gave them "my" details resulting in my phone being blacklisted!!!!
So they have now un-blacklisted my phone and updated the details on my account. still no explanation as to how it happened, but at least my phone is working again.

[Q] HELP !!!

Im having a big issue (maybe small for you techs out there)... I found a nexus 4, it was all beat up and cracked... i did contact the owner, but he said that it was too much money to fix it... I paid 200 bucks to fix it and now it looks like new... the person that had it had service with t-mobile (as i do), ... but the phone wont work with them on their network. I even replaced the sim card thinking it was mine that was bad. The phone says emergency calls only (making me think maybe it was blocked)... I paid for a code which i have not been able to input because i can even get it to go to the screen to put it... i tried to do a hard reset and nothing, tried this three methods send by the company i bought the code from
Method #1 Go to the dial screen on your phone as if you are going to make a call and press 2945#*model number#. For example, if you have an LG Prada P940 you enter 2945#*940# or if you have an LG Optimus L3 E400 you enter 2945#*400#
Method #2 Go to the dial screen on your phone as if you are going to make a call and press: 2945#*71001# Once prompt for the code enter the unlocking code you received from us.
Method #3 Go to the dial screen on your phone as if you are going to make a call and press: *#865625#
and nothing has worked so far. I called TMobile again and they told me the phone was blocked by them, and supposedly since it was a prepaid line they requested it for the IMEI to be taken off their blocked list, and that it was going to be from 24-48 hours before the phone would work...
now for the weird part, just to try something out i put my daughter's ATT sim card in it, and voila, the phone works perfectly fine without even unlocking it... makes calls, access internet, etc...
can someone tell me what the heck is wrong with the phone??
The phone is factory unlocked.. Not sure why you bought an unlock code. Or why someone sold one.
Sent from my Nexus 4
It's still blocked on T-Mobile. Call them again.

Thats what i thought too , but for some reason it does not work for Tmobile and it works for att
nothings wrong with the phone, its doing just what its supposed to. its your research about it thats a little off. someone blocked the phones imei with tmobile, so you dont get service. also, the phone is a pentaband, so itll work with most, if not all, gsm carriers. att being one of them. since the imei was blocked at tmobile, not att, it still works with att radio band.
im actually calling tmobile again as i type... i dont understand why a blocked was put on this IMEI... when i talked to the previous owner of the phone he told me he never report it damage or lost because it was a prepaid plan, and that he anyways had decided to get an iphone (suckss)

Galaxy A3 No incoming calls

hi,
I have a intermittent problem with incoming calls.
I takes my son a least 3 times to get though.
Its either engaged
rings twice and goes to answer phone
rings once then enaged
or says 'this number is unavailable'
I'm with virgin,
phoned them numerous times and they have altered the voice mail ring times and things, then decided it was the sim card.
New sim card came but was exactly the same, so more codes entered for virgin, then decide it was the phone.
Phone came back after 2 weeks saying its fix and updated but was exactly the same.
Phoned virgin again they said its not the phone or the network? so I dont know what to do.
While my phone was away being "repaired" I bought a cheap £15 phone from tesco and put my sim in it and it worked fine. Maybe its because its a simpler technology.
Any help would be appreciated

Phone Not Allowed - UK SM-G950F

Hi All
I'm at my wits end with this Samsung S8 phone, Bought a 2nd hand S8, was working fine, but I noticed the internal storage was only showing 9.63GB
Had a look on here and the solution was to stock flash the phone. I did that, all fine, storage was back to normal....BUT since then I can't make or receive any calls.
I get the error "phone not allowed" and it won't connect to ANY mobile network.
I've tried loads of different suggestions
Sim is OK in another phone
Re Flashed (numerous times)
Andriod 7 and 8
Sim and Phone OK with three network
But still have the issue....
Can anyone help me? or push me in the right direction?
Cheers
Tommy
You probably tried this, but try booting into safe mode. If it works then there is a software problem. If the problems persist in safe mode you probably gotta contact Samsung.
Are you sure the phone is unlocked?

Is the phone blacklisted? if it is blacklisted then it will not connect to service. Your SIM wil work perfect in any other phone.
Hate to say this but it does sound like your phone has been blacklisted.
You can check with one of the online IMEI blacklists.
If your phone shows Phone not allowed and a code like MM#6, it usually is an indication that it was blacklisted.
Check your phone's IMEI on a blacklist checker like http://imeipro.info/
The previous user most likely had the firmware and baseband messed around with and once you flashed stock it reverted to true state, it's highly advised to get back in contact with the person, where was the phone bought? A shop? Online?

Yeah tried that , still the same
If one is in possesion of a S8 that says "Phone not allowed", and the phone is blacklisted, is there any way of fixing that?
I have the same issue here..
I bought an S8 from Manchester last summer, and I started using it last week, (because my other phone worked longer than expected) and after I gave the phone the Network key that the previous user wrote down for me, then that message appeared.
So im stuck with this almost completely new brick aswell...
Any options at all?

The only real solution here is to either go abroad and sell the phone, or sell it to someone who is going abroad. The phone will work outside of the UK.
It does sound as your phones imei Nr is blocked in UK.. Probably the person who sold you the phone, stole it somewhere.
I have the same problem on my Samsung S7 now in Brazil.
In Canada, on Canadian carriers, everything is fine, and if I put the Canadian SIM in there everything is fine. But the minute I plug in Brazilian SIM card, boom, Phone Not Allowed message comes up and it won't connect to any of the Brazilian networks. Brand new SIM, works just fine on another LG phone (and any other phone I tried).
The phone is unlocked, I even checked with a few pieces of software and there is no network lock on it either.
I've got the master & network unlock codes from Samsung, but have no way of inputting them as no prompts for those come up when I insert the Brazilian SIM.
I checked the IMEI, it is definitely clean and not blacklisted.
Heck, I even rooted the phone to see if that would help, and still nothing.
Any idea what else to try or what else might be causing this goddamn message to pop up?!
I solved my S8.
Blacklisted on all uk networks except Three network.
Works perfect.
