Question about Sony Ericsson T610

1 Answer

SIM card when i insert my SIM card from my previous phone, it says "Insert correct SIM card." it a T-Mobile SIM card. i took it down to a T-Mobile store and the guy that worked there tried his SIM card but it did the same thing. i know the card works because i have swapped it out with about 4 different phones, all of which are differnet brands.

    and thats what i thought at first as well. i took it to a wireless phone specialist who tried many different wireless provider chips in it, but it didnt work. he also tryed to unlock it all together. nothing has worked. also, this phone was advertised as a unlocked phone.

    So what I eventually did was call the Sony Ericsson tech support number (1-866-766-9374) and asked if it was indeed locked or not. The agent on the line had me read off a couple numbers on the back to find that, yes it is locked. The agent also thought it was strange because it did not specify which carrier it was locked to. She suggested calling up the company that I bought it from ( After getting off the phone with tigerdirect, they had me send it back for an exchange. it will be here in about a week and ill post back to tell anyone who is having this same problem if it worked.

    hmmm' i think your phone need to software or re-progran to disable OTP, your phone is 4closed which means even they unlocked it it still not openline' they have to re-program it to disable the OTP....

    a possible way to reprogram it?! yes if there have a gadget and software I'm sure they will fix it. but if there's not i think replacement is the best solution for your prob.

Asha 303 goes off when i insert sim card

I assume you're having a SIM reader malfunction, or your SIM card has lost it's abilities to render your device. Please visit your local mobile provider store for more help.

Insert sim

As far as I know.there are two possibilities to get this error..

1)Sim card not inserted properly:

Try to insert the sim properly..insert it at the desired position

2)Phone may be locked with a particular network:

If the phone is locked with a particular network then you need to unlock it.You can get the unlock service for your Blackberry 9360 Curve from either your network provider or third party unlocking service provider like, and remove the network lock. Once unlocked it will work with other networks.

3)Sim Problem:

Mostly this won't be in your case because the sim had been working fine with your previous Nokia mobile and also the phone gives the same error message when you insert other sim cards.

4)Hardware Problem:

There might be some loose connection give it to a hardware service shop and check.

My pantech matrix cell phone says insert sim card

This problem arises sometimes because the mobile is unable to read the SIM. May be you should fold a small piece of paper in the same size of the SIM and keep it on top of the SIM and then insert the Battery. I think this will solve your problem.

I changed sim card, now they both display ''Insert SIM''

try taking out both cards and popping the battery on the phone.

Wait a few minutes and then turn the phone on with no card in it.

Turn it back off when it says no card found and insert the newer card and power it back up.

It seemed to keep a memory of the blank card.
