I purchased a unlocked cect i9 and it states to insert sim card how do i unlock phone?

No. Just one. You can run 2 if you want - it's a Chinese phone thing.

I guess your phone has not been unlocked yet. Unlocked phones do not have any specific carrier software and work with all GSM carriers. These include T-Mobile, Cingular and AAAA . Multi-band unlocked phones also will work with carriers in other countries.So I guess you need to unlock your phone so that u can enjoy in your country.

I see that this had been a while. The reason that your Sim cad doesn't work could be various: 1. Make sure that your phone is quad band, if it's a tri band then make sure that ATT works in 1900mhz. If it works only in 850 and your i68+ is a tri band, (which is not suppose to) then it will never work. As far as I know all i68+ original are quad band, some fakes i68+ are sold as quad band but are actually tri-band. 2. If you ATT sim card is a 3g card, it won't work either. These phones are not yet equip to work with 3g. I hope this clear up at least a little of your doubt with the Sciphone.

This phone is a POS.  Sounds like it can't read the SIM card, and therefore only 911 calls are available.

try taking the sim out and wipping it off. do the same for the prongs on the phone

Take the battery out, towards the bottom left are 2 slits (sim one and two)

The **** closest to the back is sim2 which the card goes in with the gold chip facing you, the other **** next to it is sim one, with chip facing away from you

try puttin the sim card corectly, theres 2 slots they go different just check.

Unlock code is 1122. But check to see if the sim is inserted correctly. Open both sim slots first. The bottom slot should have the sim inserted with the gold bars facing up. The top slot should have the bars on the sim facing down.

thats the whole glory about this phone is that it is unlocked. unlocked only means it can be used for any provider, any provider that has a sim card. It will only go to the provider that you are paying for, you have to insert your paid service from your sim card into this phone. It only works with services that have a SIM card. Version for example does not. This phone works with AT&T>TMOBILE etc. phones that have SIM cards. Once you place you SIM card into the phone you have to set it up for you SMS (TEXT) MMS (Picture TEXT) and if you pay for internet thw WAP settings. I pay for TMOBILE with an internet plan and that is all i am able to acess. You cannot acess any other mobile servers unless you have a paid for SIM card inserted. This phone allows two so if you pay for two providers (i do not) you could have two phone numbers with the same providers or two different. this si good for people who run business and want to keep their number and bsuiness seperate without two phones. Chill out dad!!! unlocked only means you cna use it for most cellular providers instead of having to pay for that companies phones. Example TMOBILE wants you to buy their phones. ATT&T wants you to buy their phones. But if you purchase these phones and need help setting it up you can call for example TMOBILE and they know how to set it up. Yous just have to hit the unsupported phones option. On an I9 forum site I use a guy actually said that the TMOBILE rep he was talking to had the same phone. I have a SCIPHONE I68 flashed with the I9 firmware. You can get these on ebay for 119 with and 8 gig SD card. Look for a guy named DEALZCENTRAL site (no its not me) and I recommend him. I orderd my phone on a THURS and got it on MON. Everyone else I saw was from Hong Kong and wasnt sure if i trusted that. This guy is here in the States.

i have the same problem i keep on putting my sims in (one tesco sim & one voda phone sim) and it said the same thing invalid sim. the sim regestars for about 2 seconds then it either says invalid sim or emergancey calls. whats a matter with it should i send it back.kjr2502
