How to fix my mottorola v3 its sayin no service???

Well it depends...First take a sim card beside yours, one you know works, power phone off, insert sim, power phone up, wait 1 minute, if it still says no service, power down and take the sim card back out, reinstall the battery and power phone back on without sim installed. when the phone powers back on does it say "no sim" or "no service"? this is to see if the phone can decipher a sim being in the phone and it not having service. If it say no sim then the sim reader is working, if it says no service then the phone may not in-fact be able to tell the difference of having a sim card and having service. Regardless at this point it is not working and more than likely an internal electrical component has failed and more than likely it may be the radio communication circuit of the device, if you insist on keeping this device- find one with a cracked screen but working internal and dissemble it, and replace the main board in the unit- this will in turn change the esn' imie, the overall serial of the phone, so take note of the new phone serial number- only replace the main bored under the keypad,be careful because it is VERY easy to mistakenly damage the device and its components. I do not see an easier way than this to fix you issue besides taking it in for repair- the new phone does not have to be broken but must be operational for making and taking calls. save all of your information as it will be lost after transfer-more or less still on the old phone, if this is an unlocked device please return original carrier sim for testing, and if the unit does not accept sim card skip those steps, and be sure that the new phone does not have an esn lock--Good Luck

My phone turns on then says "sim card locked" please help me

You will have to contact the supplier of your phone for the unlocking code since your phone could be locked on a particular network. If the problem has happened while on use, it could be due to bad SIM,Software fault on the such case you will need to contact the supplier or reinstall the software..

Sometimes say insert sim

you can take the battery and the back off the device and place in completely submerged in a bag of white rice and leave it in there for 1 to 2 days this will help absorb the moisture, this should fix it if the water did not damage the circut boards if the water damaged the circut boards then the device is fried

Puk blocked!!!

It is permanently blocked and you will have to purchase a new sim card. They only allow you to enter the code a few times before it is blocked in case someone got a hold of your phone and tried to use it.... A new card is about $20--- thats the only way to fix it
