Please help, I want my Samsung sgh s125g to work with other sim cards.

You will have to contact the phones carrier to have it unlocked. There terms of use you must abide by before they unlock the phone. Also make sure the sim is the proper one. For example cdma, GSM, 4g, 3g, LTE. Most sim cards are also locked to there specific carriers and phones sim cards can not be used or swapped out to a new phone. The phone may just not work with a different carrier also for the fact that it is a cdma phone and may not work on other carriers frequency's. If it is from the original carrier they will need to have some more info off the phone like IMEI number. That number is on the carriers network and is used as a identifier of the phone and to be used to lock it to them and the sim card.

Samsung SCH R820 I would like to unlock it from metro to T-Mobile

As far as I know, Metro is a CDMA wireless carrier, T-Mobile is GSM. Your Samsung SCH-R820 works on CDMA, which don't need a SIM card to work. GSM technology does need a SIM card to work and make calls. As you can see, there is no way that you can use a CDMA phone with a GSM wireless carrier.
There are new high tech phones that works both, CDMA and GSM, these are called World Phones. Sorry, and best of luck.

So i have an unlocked phone and i put in on a carrier but i now want to change the do i do it?

What is the model of your mobile phone? If your Tracfone SIM is an active and GSM SIM it must be automatically read by your mobile phone. What message does your mobile displays when inserted a Tracfone SIM to it?
I think you have not unlocked your mobile properly. How did you unlock it? Unlocking a mobile phone using unlock code is the best way to unlock. You can get the unlock code for your mobile phone from at very low cost.

Bought blackberry strom 9530 from US. Already Unlocked it. GSM sim is working on it. When I switch to Relaince CDMA sim it says call failed.

Even if the phone is already unlocked, the phone may still not be able to work on any CDMA carrier, as the unlocking process only allowed you access to GSM carriers.

Have LG900G tracfrone want to switch it to ATT have new sim from ATT phone reads Sim Lock Code-1 ? ATT rep says phone needs to be unlocked?

Hello, you can't simple change your old sim card with new sim card from another mobile provider without unlocking your phone first. You can request LG 900G unlock code from tracfrone and you must pay some bucks (up to $80) and wait for a couple of weeks before you get that unlock code. If you on tight budget or you want to saving up your money, you can buy lg unlock code from third party sites and you don't need to wait until a couple weeks to get that code. Just in a few minutes.

What is the meaning of cdma? is it normal sim card

In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access(CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs.

How to remove the phone lock code for sony w200i

Many cellular providers around the world lock their phones so that they cannot be used on the networks of other providers. Unlocking codes remove the lock and make the phones usable on any other network that utilizes the same type of technology.
  1. Phones that are locked to specific carriers use devices called Subscriber Identification Module (SIM) cards that are provided by the carrier at the date of activation. Only phones on a Global System for Mobile communications (GSM) network use SIM cards. GSM is a standard that was started by the European Conference of Postal and Telecommunications Administrations in 1982, adopted by over a dozen European countries in 1987, and then finalized in 1989. GSM is now the most used typed of cellular network in the world.
  2. Function
  3. A locking code prevents a phone from working unless it is using a SIM card from a specific company. The lock forces customers to purchase only phones and SIM cards from their cellular carrier or from specific manufacturers. Phone locking codes can also work as a security measure by preventing thieves from using a stolen phone if they are trying to use a SIM card from a different cellular carrier.
  4. Geography
  5. There are no laws covering locking codes for mobile phones in the United States, Spain, and the UK, so each GSM company in those countries has vastly different policies regarding them. Both Singapore and Belgium have outlawed phone locking codes and France has laws in place that compel cellular carriers to provide the unlocking code to their customers once they have only six months remaining in their service contract.
  6. Types
  7. You can acquire an unlocking code for your GSM phone in several different ways. The most common method available is to contact your cellular provider's local office and ask for a code that you enter directly into the phone's settings menu. You can also call your cellular provider's customer servicemag-glass_10x10.gif office and have them send an over-the-air update that automatically unlocks the phone. A few companies also offer services that allow you to mail in a phone so that their technicians can enter the unlocking code and then mail it back to you.
  8. Considerations
  9. Cellular providers in the United States are not required to give you an unlocking code, so many only offer them under specific circumstances, such as if you move out of their coverage area or your service contract ends. You can also obtain unlocking codes for certain types of phones from other sources such as websites or third party phone companies.
