Hi @abrannon ,
I would not suggest purchasing an additional concurrent connection if your objective is to add more data. As you’ve pointed out, the overage data is more cost effective than the additional concurrent connection.
Talk2M Pro is a credit based service. When you purchase the Talk2M Pro Service (PN: TM50041) you receive enough credits to last you exactly 1 year if your usage is under the defined limits. If you exceed the defined limits, you will draw down your credits faster than 1 year. To account for these overages, you can preload your account with more credits by purchasing multiple of the TM50041. These credits are added to your Talk2M account and the credits do not expire.
In short, purchasing multiple of the TM50041 Talk2M Pro Service Credit Packs is the most efficient solution to this problem.
