                                AMENDMENT NO. 2

     This AMENDMENT No. 2 (the "Amendment") is made and entered into by and
between GoAmerica Communications Corporation ("Customer") and Cellco
Partnership, doing business as Bell Atlantic Mobile ("BAM") for attachment to
Contract ####-##-####, dated May 13, 1997 (the "Agreement").

     1. This Amendment is an integral part of and modifies the Agreement. The
terms used herein which are defined or specified in the Agreement shall have the
meanings set forth in the Agreement. If there are any inconsistencies between
the provisions of this Amendment and the provisions of the Agreement, the
provisions of this Amendment shall control.

     2. Exhibit A, is hereby deleted in its entirety and replaced with a new
Exhibit A, in the form attached hereto.

     3. A new Exhibit B-2, "Pioneer Price Schedule" is hereby added in its
entirety as attached hereto.

     4. A new paragraph is hereby added to Section 3, "Pricing" as follows:

"In order to qualify for and receive the rates as shown in this (Amendment),
Exhibit B1, "Pioneer Price Schedule," Customer shall provide a pre-payment of
$[**], to BAM for charges associated with Customer Contract ###-##-#### to be
deposited in an account associated with this Contract Number prior to BAM
activating any NEIs on this plan. As NEIs are activated and charges are
incurred on this plan, BAM may draw down these funds for any and all charges or
fees incurred by Customer. If at anytime the BAM account associated with this
Contract Number is less than $[**], Customer shall, within [**] of written
notification from BAM, remit payment to achieve a minimum amount of $[**] in
the account. Upon non-payment of any sum due BAM, or upon a violation by
Customer of any of the provisions of this Agreement, BAM may immediately upon
written notice deny any further NEI activations from Customer without
incurring any liability. In the event that after [**], Customer fails to make
minimum payments required to achieve $[**] in the account associated with this
Contract Number BAM may immediately upon written notice temporarily discontinue
or interrupt the furnishing of the Service to the Customer. Any failure to
achieve the $[**] minimum threshold on a timely basis shall be considered a
breach and BAM may pursue any and all of its rights including termination of
service and termination of the Agreement."

If at the conclusion of the extended term of this Agreement, Customer wishes for
this Agreement to automatically renew for an additional one year term as
specified in Section 15, Term of Agreement, and continue to take advantage of
the rates shown in Exhibit B1, it shall be required to maintain a minimum of
[**] active NEIs per month. If such minimum is not maintained, Customer shall be
charged the difference between [**] and the actual number of active NEIs, on the
following month's invoice. NEIs active on rate plans other than the plan shown
on Exhibit B1, shall not be included for the purpose of determining whether
Customer has met its monthly minimum."

     5. This Amendment shall be effective when executed by both parties.

     6. All provisions of the Agreement, including attachments thereto, not
addressed by this Amendment remain in full force and effect.

IN WITNESS WHEREOF, and intending to be bound hereby, the parties affix their
signature to this Amendment.
