The iPrimus Mobile $19.95 Saver Plan (SIM Only) includes $350 of credit for standard calls and text, making this plan ideal for medium users, who use their phone every day, make 50-100 calls, send 50 text messages and who don’t need to access the internet from their phone. iPrimus offers this plan on a bring-your-own (BYO) basis, which is great value for customers who already have a phone or who prefer to buy outright. The iPrimus Mobile $19.95 Saver Plan (SIM Only) is on a month-to-month contract, which is perfect for customers who don't want to be locked in.
