Nov 21, 2003 /FW/ --Starting Monday, a new federal rule takes effect that allows consumers to switch telecommunications carriers without changing phone numbers.

Local number portability, or LNP, is an important issue for people who rely on their wireless phones as a main line of communication. Below are some tips to keep in mind before making the switch.

• Determine your obligations. Check with your current carrier on contract termination fees and invoice balances under your current contract. If you're making the move to another carrier, early termination fees may apply. Check with your current carrier if you are uncertain when your contract ends.
• Be prepared to experience some possible delays as you make the switch. LNP is an intercarrier process requiring the cooperation of your previous service provider, and new activations involving a ported number will take longer than traditional wireless service activation. If the transfer process goes smoothly you can expect to be active on your new wireless service provider's network in a matter of hours.
• If you do switch, you'll likely need a new phone. You can take your number with you, but your old phone probably won't be compatible with your new wireless provider.
• Consider the "bundled" services approach. To lower overall costs for telecommunications, put your calling into a bundled package that combines local phone service with long distance and wireless.
• Keep in mind that not all numbers may be transferable. Not all numbers can be transferred in all markets and by all providers. Initially, LNP will only be available in larger markets.
• Continue to use your current phone until your new phone is fully functional. Service to your old phone will be automatically disconnected once the number has been transferred.
• Have a copy of a bill from your current service provider on hand. When processing your transfer request, it's important that your new service provider correctly enter information from your account, like your name, address, account number and phone number. If the information doesn't match, the request to transfer your number may be delayed.
