You will need a sim unlock code for this to work. You can get them online for $3 or from your carrier

Changed carriers installe there sims card now unit not working


Unless your phone is unlocked, sim cards from a different carrier won't work. See if your new service will unlock your phone.

My girlfriend is only getting some text messages i can text her 3 diffrent things and she wont get any or will just get one.. its not only me t'ho shes other people have told her same thing..


Phone or sim card could be faulty, try sim card in another phone on same network, and try phone with a different sim card from same network. If messages come through with a different phone then the original phone is faulty, if new sim card gets messages then the sim card is faulty. Hope this helps.

How do i fix my ZTE to to read sim card


If your ZTE is unlocked you can use different sim card from different vendors, otherwise you can only use the same service provider.
Verify that the sim is in good condition, using another ZTE, etc.

I am going abroad and have a pay as you go phone. Can I change the sim card in the next country?


yes both aus and nz need quad band phones however be carefull which sim card you choose as some networks require phones to have other chips in them. It may also be worth trying a couple of different sim cards before you leave to make sure your phone is "unlocked" for other networks. If not, you will need someone to unlock it for you.

have you tried using different Sim cards? check if the network status is made offline,if yes change it.if you have a Sim card inserted and when you change the profile to general it shows that 'please insert a Sim card' ,think that your sim needs to be changed.try using another Sim card and post the result here.

Why I don't have network signal on my nokia 6600?


If you are not getting any network from your phone it my be be due to:* sim card issues* network / outage issues* phone issues
SIM Card issues:1. turn off mobile phone2. remove battery3. remove SIM card and memory card4. clean the SIM card from any dirt or dust5. wait for 2 minutes then plug back battery6. insert memory card and SIM card properly7. turn on mobile phone8. check if you will be provided with a signal from the upper right corner of your phone's screen. if not, try a different SIM card.
Outage:1. call your service provider and confirm if there are outages in the area or outages from the BTS where your SIM card is registered.
Phone Issues:1. if the phone is open line, try to enter a different SIM card2. try to insert the SIM card into a different phone, check if it will be provided with a signal3. if the second phone still dont get any signal and your service provider stated that there is no outage that may affect signal issues from your phone, check it from them if your sim card is still active.4. last resort is asking for a SIM replacement with the same phone number

I can't use my Nok 5230. I get a message: SIM card registration failed. I tried the SIM in a different phone and it's worked and I tried an other SIM in the Nok 5230 and didn't worked too. What can I...


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

I can't insert other sim cards from this certain network


Sounds like the phone hasn't been unlocked properly. I had a similar problem and eventually just changed my sim to the original phones network. This solved all problems but i don't know wether this is the full solution to your issue. I tried to help best as though dude.
Cheers.
