Problem making and reciving calls

Bought a phone 2 months ago then after 3 weks it stopped sending and reciving calls and inactive sim started showing on the screen!
I dont think its been blocked or barred as i was initially told by the shop where i had it unlocked, as i ran a quick check,
so are there any other causes of this kind of thing?
the phone is a sony ericsson c905 and everything else is working fine on the phone apart from the i can,t make or recive calls!
p.s. the sim is working fine in my old phone so no problems there!

I have a sony ericsson J10i2, I bought it off ebay, it's saying i have an inactive sim, and there's a handset next to the network bar with a red line through it. I have signal on my phone, but i can't make...


Hello and Welcome to FixYa!
Inactive SIM message may arise due to more than one issues. First things first check the hardware of your phone, to do this Put out the SIM card and check what happens. If it shows insert SIM card, its normal. If it shows the same inactive message then hardware malfunctioning.
Ok if the hardware is ok, then its simple. Inactive SIM means that your SIM card is not being able to register your Network carrier. The Phone with a red-line means SIM card registration failed. Although the signal radar works. This may be due to 2 issue; either there is a issue at the Service provider End, to check this call the service providers from other cell or land-line and check the status of your connection against this SIM Card No. If they say everything is ok. Then Its confirmed that your Phone is Network locked (Can only be used for one specific network) In this case coordinate with the seller.
I hope you will have a clearer picture now.

If you have any Confusion, questions or issues regarding your problem do tell me.

Inactive sim is usually related to your SIM Card, you should try reinserting your SIM card again, to see if it works, or simply insert your current SIM card into another phone to check if there is any service. should both failed. It should be your SIM card problem, you can contact your service provider or carrier to have a replacement SIM.

Inactive usim


The same thing happedned to my one. I switched the phone off then on and it worked. If it still doesn't work it is probably not the right simcard. Also the dude at the shop when i bought it put the sim in 4 me. Their was a sim in the box for the mobile.

My SGH-T629 came from the U.S. how can i make it capitable with the sim card in the phillipines


A. Turn on phone with full battery and non-T-Mobile SIM in place.
Allow phone to completely boot up to Wrong SIM screen. B. Enter from Wrong SIM Screen *#7465625# to confirm lock status C. Scroll through Interrogate Screen 1. Network lock - Active (this is the one you'll be deactivating)
2. Subset lock - inactive
3. SP lock - inactive
4. CP lock - inactive
5. SIM Card lock - inactive
6. Activa lock - inactive
7. Auto network lock - inactive
8. Auto subset lock - inactive
9. Auto SP lock - inactive
10. Auto CP lock - inactive
11. Auto SIM Card lock - inactive
12. Phone lock - inactive D. Push "C" button under navigation button to clear Interrogate screen back to Wrong SIM
screen E. From the Wrong SIM screen enter the following: *7465625*638*00000000*00000000# Those are two series of eight zeros. The phone will not show the zeros but will show dashes in their place. Phone may make a small tone and at the bottom of the screen it will read "Network Personalized" or perhaps "Network Already Personalized" F. Now input the following from whatever screen shows up: #7465625*638*00000000# (again this is a series of eight zeros) Phone may make small tone and will read "Network Lock Deactivated" G. Turn off phone
H. Re-start the handset and allow it to reboot.
J. Enter from Standby Screen *#7465625# to confirm lock removal status K. Scroll through Interrogate Screen 1. Network lock - inactive (note that this lock is now inactive)
2. Subset lock - inactive
3. SP lock - inactive
4. CP lock - inactive
5. SIM Card lock - inactive
6. Activa lock - inactive
7. Auto network lock - inactive
8. Auto subset lock - inactive
9. Auto SP lock - inactive
10. Auto CP lock - inactive
11. Auto SIM Card lock - inactive
12. Phone lock - inactive
That's it. Your phone is ready to accept SIM cards from just about any GSM mobile telephone service provider in the world. If you received a "wrong password" message you will need to insert a working SIM and reset the password to the default 8 zeroes "00000000". After that you may try this process again and it should work.

Inactive USIM


When i got my KU990 i got a new sim with it but i had to ring up my network provider and they gave me instructions to enable it. Basically they have to send a signal to your new sim so you put the phone on and the sim in then they tell you not to play with the phone for an hour or so while this is happening. It also makes your old sim card un-usable other wise you would have 2 sims with the same number.

First, have you installed your SIM card? These phones have spaces for 2 SIM cards, but will work fine with only one. Make sure your SIM is installed.

After you SIM is installed in either the #1 or #2 dock, you'll have to disable the other SIM port in your "Settings" menu.

Good luck!
