Leverage messaging to easily manage your device fleet

Hologram’s SMS service enables you to send and receive messages from your devices connected via a Hologram SIM card and get immediate notification of events that may require your attention. The SMS service works between any carriers and any devices that contain the Hologram SIM card.

How does it work?

Phone numbers are not necessary to deliver an SMS via API calls or via the Hologram Dashboard. However, Hologram offers phone numbers that you can associate with your Hologram SIM card. A phone number allows you to easily send an SMS message to your device from another SMS-compatible device, like another cell phone. Hologram phone numbers are not enabled for voice calling.

Can you set SMS limits?

Setting SMS limits is a way to limit the number of outbound SMS messages a device can send during a billing period. SMS limits are commonly used to protect your SIMs against fraud and theft, or lowered to limit unexpected charges.

Upon reaching the limit, your SIM will be paused by the system and the organization owner will receive an email notifying them of the pause. This means that the SIM can no longer send SMS or data until the SMS limit is increased or until the next billing period begins.
