Can I Just Switch Sim Cards Between Boost Mobile Phones. Can I Just Swap My Old SIM Card For A New One If I Get A New Phone. I understand I may have to take them in to a store or call CS and there may be a charge but I really just want to know if one can do that.
You can also use different phone service plans in a single unlocked phone say one for work and one for personal by switching the SIMs. If a phone demands an unlock code to access it it has nothing to do with a SIM card whatsoever. Well there are three different sizes - standard micro and nano.
The sim card is like a key that gives your phone access to the cell network also identifies that phone number and account the phone is associated with.
Find your phones IMEI or MEID DEC number by opening up the phone dial pad and pressing 06 If this does not work then you can look under the battery phones with removable batteries only or in the phones settings menu. In contrast only SIM cards from a specific cell phone company will. With unlocked phones you can always switch your phone service between different phones as easily as popping out the SIM card and moving it. The only question is where on the phone you can access them.
