I anticipate going the pre-paid route when the successor to the GNex is released. I originally had my eye on 3 different MVNOs: Straight Talk, Red Pocket, and T-Mobile. I've ruled out Straight Talk because they seem far too draconian. Here's what I've found that stood out:
TERMINATION OF SERVICE: "Either party may terminate this Agreement (which will terminate the provision of Straight Talk service) at any time. Any unused service at the time of termination will not be refunded. Straight Talk may terminate this Agreement at any time without notice if we cease to provide service in your area. We may interrupt or terminate your service without notice for any conduct that we believe violates this Agreement, if you behave in an abusive, derogatory or similarly unreasonable manner with any of our representatives, if we have reasonable cause to believe that you are using your Straight Talk phone and/or wireless service for an unlawful purpose or in a way that may adversely affect our service, if you engage in any deceptive or unfair conduct with respect to your Straight Talk phone and/or wireless service. Any provision of this Agreement which by its context is intended to apply after termination of the Agreement will survive termination, including, but not limited to, any restrictions on the use of Straight Talk phones."
6. STRAIGHT TALK UNLIMITED TALK, TEXT AND MOBILE WEB ACCESS PLAN INTENDED USE: Straight Talk Unlimited Talk, Text and Mobile Web Access Plans may ONLY be used with a Straight Talk handset for the following purposes: (i) Person to Person Voice Calls (ii) Text and Picture Messaging (iii) Internet browsing through the Straight Talk Mobile Web Service and (iv) Authorized Content Downloads from the Straight Talk Mobile Web Store. The Straight Talk Unlimited Plans MAY NOT be used for any other purpose. Examples of prohibited uses include, without limitation, the following: (i) continuous mobile to mobile or mobile to landline voice calls; (ii) automated text or picture messaging to another mobile device or e-mail address; (iii) uploading, downloading or streaming of audio or video programming or games; (iv) server devices or host computer applications, including, but not limited to, Web camera posts or broadcasts, automatic data feeds, automated machine-to-machine connections or peer-to-peer (P2P) file sharing; or (v) as a substitute or backup for private lines or dedicated data connections. This means, by way of example only, that checking email, surfing the Internet, downloading legally acquired songs, and/or visiting corporate intranets is permitted, but downloading movies using P2P file sharing services and/or redirecting television signals for viewing on laptops is prohibited. A person engaged in prohibited uses may have his/her service terminated without notice or a refund.
The fact that they appear to limit what you can actually do with your "unlimited data," on top of the fact that they can cancel your account without notice, thereby causing you to lose your number, is enough to keep me away. I'd rather pay a little more with Red Pocket or T-Mobile and know exactly where I stand.
