Low cost sim cards with pricing structure designed especially for "Do It Yourself Security Systems"
This is the large size sim card not micro.
You have bought an alarm system not a cell phone. Why should you worry about multiple calls being made by your alarm system when it should only make a call when there is a problem.
With prepaid plans you are charged for minutes that if you do not use in a certain amount of months then you lose those minutes and you have to purchase more. With our plan you are charged as little as $4.00 a month.We understand you need to save money and that's why we created a specific plan for GSM Security systems. These sim cards are on the T-Mobile network and are designed for SMS and Voice services only. These sim cards are perfect for security systems since you should not need more than 4 calls or texts a month. No need to buy airtime. Each month your credit card will be debited your monthly fee and you will receive an invoice for overages based on your plan.
You are allowed 10 voice calls or SMS message a month. Anything over that amount is billed at $.25 per call or text.
