Yes, you have correctly assessed the situation with your account. As of November 1st, you had 8 active systems in your account, and 16 tokens to draw from. Each device in ALMS consumes 1 token per month. As you sate, you will be out of tokens in January. Once your account goes into a negative state, we suspend access to your account until you purchase more.
You can purchase tokens from your Authorized Sierra Wireless Partner. They are sold as a “Service Pack”, which contains 12 tokens (one year of access) for $20 per Service Pack. I would suggest purchasing at least 8 Service Packs for your account.
In addition, when you purchase new AirLink gateways and routers and register them for AirLink Complete (https://www.sierrawireless.com/complete/register/), you receive access to ALMS for one year. We add 12 tokens (one year of access) for each registered device to your account automatically.
I hope this answers your question, but please reach out to us if you have any more questions.
