Term "Cell phone" is used instead of "Mobile phone". If you want to use your Pakistani phone in USA you can easily use it. There are few things you need to know that are mentioned below.
- Pakistani cellular companies use "SIM cards" as all companies are GSM however in USA only two companies provides GSM services AT&T and T-mobile so you can use their services easily on your cell phone.
- All mobile phones in Pakistan are unlocked and can easily be used for Mobilink, Warid or Telenor etc however only in some rate cases if your cell phone is only locked with one provider say Mobilink (As Mobilink announced some cheap mobile packages in past that were only locked with Mobilinik) then you need to unlock it to use it with any other service provider even in USA.
- If you would like to use some other cellular company that provides CDMA technology you will not be able to use your cell phone that takes SIM card with that network in that case you can easily sell your cell phone for a very good price as used cell phones that are unlocked are sold at higher prices in USA.
