I do not know why it says SIm card can only be used on specific networks no matter what card I put. I was asked to contact for the unlock code.

It depends which 810 you purchased. Some are "unlocked," meaning you can use it with the service provider of your choice, but some are "locked" to a particular service provider (i.e. T Mobile). I actually paid a little more for an "unlocked" 810. But perhaps if you contact Nokia, they can tell you how to unlock it.

You need to contact your carrier's network to verify whether or not the carrier's network allow the use of SIM cards. For Instance, Straight may accept the use of SIM cards only if the telephone was previously carried by a network that allows the use of SIM card such as Simple Mobile or T Mobile. You also need to verify the specifications for your particular telephone : A CDMA network used by Verizon, U.S. Cellular, and Sprint; or a GSM network used by T-Mobile and AT & T. Some cell phones are designed to use both networks (CDMA or GSM).

the sim card i used was from att so you can use a card from a different carrier as long as its supported by the phone. I think on the product page it tells you which phone services it supports.

I tried that as my sister borrowed my phone and as soon we placed the SZ card of TMobile , it still asked us to contact the provider which is the T-Mobile. We were not able to use it,I even bought 2 of them.

This is a phone that is on a CDMA network if you have the same network their you can use as long as they will program it on their network. We do have sims card phones as well and those are on the GSM network and most country's use this network system. so please check with your provider for more assistance with activation of this device. Thank you valued customer.

Peter,According to the vendor (RoamtheWord) I purchased it from, the unit suppose to be permanently unlocked but it started acting up and when I master reset it, the unit refused to work with another wireless sim card so if your unit is unlocked - "never master-reset the unit" - send it back to the vendor. You can try AT&T; to unlock the unit if it will not accept another wireless sim card but it is not guaranteed.

Inserting a sim card in an unlocked phone does not lock it, ive had a n95 an iphone an e71 and a 5800 all are still unlocked

my phone was unlocked when purchased. I found that if you change the direction that you put in the sim card it should work.

Every Net10 phone that I've had (I've had 6 in 3 years (I'm rough with phones)) I've had to use the new sim card that came with it. If you put in the one from your last phone, it will tell you that it's not a valid sim (or, that's the experience I've had... yours may be different!)

Your network carrier(s) should show up there. Not that it matters. There is nothing you can do with that selection. If nothing shows up you probably do not have a carrier (SIM card) set up.

Due to different configurations in carrier networks - some carriers SIM cards may not work properly. A SIM card capable of operating on a 2G network is required.If you choose to use an AT&T; SIM card it may be required that you call AT&T; to have your SIM card "Unlocked" so that it may work with multiple phones and not just the phone it was originally registered with.The current list of carries with known issues is:Boost MobileTracFone4G SIM cards

Best I can figure it's that you might not be able to use US Sim cards with it. Check with your provider before buying it.

SIM modules are always locked to a company either through a contract or a pay as you go. If the phone is unlocked you can plug a SIM from any company, the only thing to take care is the size of the SIM. Take into account that not all phones work on all networks, while voice service use to work for all companies since they use to be multifrequency, data services are different, T-mobile and AT&T have different standards to the others.
