I have 5 lines and all with the 5.99 Tzones unlimited web. The phones on those 5 lines are: N900, N82, Nokia Nuron, Nokia Nuron, HTC HD2. Step 1: Call Tmo and ask for CUSTOMER LOYALTY (DO NOT tell Customer Care that you are trying to change your data plan. CC CAN give you the 5.99 Tzones but most CC reps will put up a fight so to avoid nasty notes on your account, just ask for Customer Loyalty Department) Step 2: After the CLD rep says "Thank you for calling T-Mobile, my name is......" You respond, "Hello (CLD Reps name), my name is (your name), How are you today?" That will soften up almost any CLD Rep into helpful tone of the call. Step 3: Proceed to tell the CLD Rep that you are calling to save money on your lines (True, we all are trying to save money) and that you were told that you needed to speak to someone in the Customer Loyalty Department to have the Granfathered $5.99 Tzones Internet added to your line(s) and that Customer Care transferred you over to them (CLD Rep) You have to be sure you know WHY you are calling. Step 4: You may get a response from the CLD rep that will just place you on hold and add the $5.99 Tzones Web right away or they may just try to explain the (false) benefits of the plan that you have with "smartphone" data plan and how you won't have access to the full web (false again). Just reaffirm the CLD Rep that all of that is ok and that your main concern is saving money yet still having *basic* access to the web and email. Step 4: Just incase you get Johnny "By the books" Rocket who sticks to his fresh training material that says $5.99 Tzones is not compatible. JUST AGREE TO EVERYTHING AND CHANGE NOTHING ON YOUR ACCOUNT AND SAY "THANK YOU FOR TRYING TO HELP" and then call right back and start at step 1. Customer Loyalty's job is to keep customers happy at all costs so that they will stay with tmobile. Never get angry with them and always call back. They can help when no one else can. Step 5: Once the CLD Rep has added the $5.99 Tzones Web to your line(s), proceed to thank the Rep several times in a show of gratitude that they have helped SAVE you money and keep your lines. That will go a long way and not only is it true but it makes the CLD have a job well done. Facts about the $5.99 Tzones Web: It overrides the $9.99 Tzones Web AND the "Smartphone" Dataplan. By override, I mean that the old Tzones plan does NOT contain any splashpages that tell you to upgrade to another data plan. It is THE internet plan that is "above" those other dataplans. It works with ALL unlocked phones that can be used on Tmo (with correct settings) and will work as if it IS the higher priced data plans. The $9.99 plan will tell you to upgrade to another plan based on phone model. The $5.99 plan is exempt (for now and has been since its designation as Granfathered: Thats the Granfathered Benefit, Overrides newer data plans.) EXCEPT....... 2: OS Specific Data Plans: $5.99 Tzones Web does NOT override Android, Blackberry and SideKick data plans. Those data plans are on a different Tier than the Smartphone Dataplans and cannot be overridden for that very reason. I hope this helps someone save money. This has helped me for more than 2 years of the 4 with Tmo. I have dropped the granfathered plans, gotten them back, switched to Android, gotten them back, closed lines, opened new lines and got it back again. All by just telling the truth that the Customer Loyalty Department has free will to add this plan and that all I wanted to do was save money on my account while having basic internet usage. (browse the web, check email).
