  • Porting AT&T Landline Phone to Google Voice

    Posted on October 4th, 2011 wt8008 2 comments

    In my previous post, I explained how I purchased a Obi110 for use with Google Voice. I am porting my landline phone to Google Voice for use with my Obi110 and some features. I have to first port the landline to an intermediate cell phone provider (T-mobile), since Google Voice only supports porting in from cell phone providers. (See the link in the reference section for detailed instructions.)

    Currently, the AT&T landline bill is about $28 after all fees and taxes. The landline itself is about $20 and the remaining $8 consists of taxes and fees.

    Timeline

    This is the timeline of events for porting.

    • Thurs 09/22/2011 08:28 PM – Order Placed for prepaid SIM for $7.57
    • Fri 9/23/2011 – Shipped
    • 9/24 – 9/25 Weekend
    • Tue 9/27/2011 Afternoon – Arrived
    • Weds 9/28/2011 Afternoon – T-mobile Prepaid Online Activation, did not take long, does ask for a cell phone IMEI. I’m sure it doesn’t matter what you put in there.
    • Weds 9/28/2011 12:45pm – Call T-mobile Porting Department at 1-877-789-3106, right after activating. The call took about 8 minutes and I received a reference number to the porting request. It was stated that it could require 3 to 10 business days to port, but it may be faster.
    • Thurs 9/29/2011 06:45 PM – T-mobile asked to call them regarding the port. The porting department did not have my prepaid number on file and needed to know it so they can replace my cell number. My landline number was also released by AT&T to allow for the porting to begin. T-mobile activated and said that calls will slowly go to T-mobile over the course of 2 to 24 hours. For a period of time calls went to either the landline or the cellphone.
    • Fri 9/30/2011 8:30 AM – Begin port to Google Voice. The prepaid account number is the landline number with area code. Also dial tone for the landline was lost.
    • Fri 9/30/2011 12:38 PM – Email from Google regarding incorrect PIN. Resubmitted Prepaid PIN.
    • Sat 10/1/2011 8:30 AM – Email from Google notifying port completion.
    • Sat 10/1/2011 10:00 AM – Tested phone service to verify functionality.
    • Verify with AT&T that the landline has been canceled.

    It required two days to finish the port from the evening of 9/29, all day on 9/30, until the morning of 10/1. I did not try to receive calls on the prepaid phone during the port to Google Voice. Callers were directly placed into T-mobile voice mail. Make sure to check the voice mail box before the port is complete. Press * to interrupt the greeting and then the last four digits of the landline number as the voice mail pin.

    Costs

    It will require 2.5 months to break even assuming free calls, which is currently true, see the summary table below.

    Obihai 110 $42.99
    T-mobile Prepaid $7.57
    Google Voice Port $20
    Total $70.56
    Time for ROI 2.5 months

    It is unknown if free calls will remain beyond 2011.
