How much do you pay monthly for a Pocket WiFi?

As a professional practitioner in the realm of cryptocurrency and finance, I'm curious about the practicalities of digital nomads and remote workers. Could you elaborate on the cost associated with a monthly Pocket WiFi subscription? I understand that for those working remotely or traveling frequently, having a reliable and portable WiFi solution is crucial. So, what is the typical monthly expenditure for such a service? Is it a fixed fee, or does it vary based on usage? And how does it compare to other connectivity options? I'm keen to hear your insights.
