All Flextel numbers, except for 0800 Freephone numbers, are currently applicable for Monthly Plans. In general, we do not recommend having a Monthly Plan for 070 or 0871 numbers as most destinations are free of charge on those ranges. The same applies for 0844 numbers, unless you are receiving international calls through them.
