Section 25

We may change this Agreement at any time (but see Service 
Plans). Any changes to the Terms are effective when we 
provide you with notice. If you use our Services or make any 
payment to us on or after the effective date of the changes, you 
accept the changes. If you do not accept the changes, you may 
terminate Services (but see Termination; Changing Service 
Plans). For purposes of the Agreement, "use" includes keeping 
the right to access the Sprint PCS Network by not terminating 
Services. You may not modify the Agreement except for your 
Service Plan (see Termination; Changing Service Plans).

You may be eligible for a fixed length Service Plan ("Term 
Service Plan") or for a month-to-month Service Plan ("Non-
Term Service Plan"). We determine the Service Plan for which 
you qualify. We may offer non-identical Service Plans to 
different individuals or entities. Services and coverage under 
some Service Plans may be more limited as compared to other 
Service Plans. Your Service Plan sets out the charges for 
Services and is your Service Plan until that Service Plan is 
changed, you switch to a different Service Plan, or your 
Services terminate. Your Service Plan may require that you 
make a deposit, prepayment, or a series of deposits or 
prepayments, or be subject to an account spending limit, 
before Services are activated or maintained.

If you are on a Non-Term Service Plan, you may change to a 
different Service Plan for which you qualify by contacting us. 
Any change is effective at the start of your next full invoicing 
cycle unless otherwise specified by us at the time that you 
place your change order. If you change or add a different
