We recommend an AT&T SIM card as their data package has unlimited text and photo messaging for only $19.99 per month.
The camera was designed with this concept.

It does not matter which cellular company offers the best coverage in your area. Verizon and Sprint network providers use CDMA technology and the camera requires GSM technology (AT&T or T-Mobile) to operate.

AT&T customer service representatives are not trained to recognize a SIM card that can function in a wireless camera. They will debate this application is possible and deny such a plan exists. Please take this manual to your local AT&T corporate store and follow the steps under Purchasing a SIM Card or Replenishing a SIM Card (page 22 of the manual) to successfully purchase and/or replenish your AT&T SIM card.
