I have a brand new orange rio, and i've just inserted the sim card that has come with it, and it says 'registration unsuccessful' and then it says 'invalid sim' in the corner? this sim card and mobile are brand new, how can i sort it out?

When the message sim card registration failed comes up it is usually as a result of one of 2 things the first being that the phone has not recognized the sim card due to an improper fixing or the sim card has become faulty. Simply try the sim on a different mobile device to determine if the sim card is still good.

Hope this solution has been helpful?

Insert any sim and try using these codes #pw+123456789+1# #pw+123456789+2# #pw+123456789+3# #pw+123456789+4# and follow onscreen instructions

If your phone displays the 'Invalid simcard' then your phone is currently locked to particular network. You need to unlock to use it with other network.
There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website Unlock-zone.com which is doing good service and they were recommended highly in the cell phone forums.
I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.

Hi by what you have said ,to me it sounds like the hand set is barred,if the phone was bought from new i would take it back if it is a second user phone they may have reported it has lost, but try another sim in the phone it may not like that sim.
hope this helps.

this is most common when your phone is a branded phone that has been unlocked(branded being it was made to work with a particular network but was unlocked and can now partially work with other networks). in this case, the phone may find it difficult to recognize your sim card, the way the phone is made is in such a way that when a sim card of the network it is branded to is inserted, it would register it straight away but in a situation where it does not recognize the sim card, it is unable to register it. this brings about the sim registration failed.
sometimes you may lose service on your phone too depending on the level on your sim card.
if it happens that the mobile phone was not branded to any network before, then you have to change your sim card to a more developed one(maybe you get a replacement from your network provider because they produce sim cards differently.like the previous ones may not have some features or have a high level of attention and therefore needs to be changed with a more recent one)
hope this helped you? please rate

sounds like phone locked on orange network

If it showing you that sim card registration failed then then make sure your sim card is work or not. if your same Sim card works in different phone. it could be that your phone has been blocked by the network

Factory resetting the phone will do absolutely nothing with this problem

There are 3 causes of Sim Card Registration Failed, when you first turn on the phone, the sim card attempts to connect to the network if it can not do this it gives a message like Sim Card Registration failed.

1, The sim card is turned off (is it Orange) if you have had the sim card for a while and it hasnt been used they will turn it off, you need to contact them from another phone to get it turned on or get a new sim card.

2, The phone has a hardware reception problem, when it attempts to register itself with the network it can not... There is a reception problem and it requires repairs, this isnt really an easy diy job on this handset.

3, The phone is blocked, i.e reported lost or stolen. Some networks when a phone is reported will allow it to get reception but will not let it make calls, however other networks will not give it reception at all and hence you get a Sim Card Registration failed message.

I hope this helps, these are the causes of the message.

turn off your phone, get the sim card and reinsert again, and then restart your phone, if not work try to test it with other simcard, check also the simcard holder if something is blocking it, clean it if its dirty, if it not work have it for a cellphone repair
