How to find the best mobile phone plan

Choosing the best new mobile phone plans is a combination of the following factors:

  • setting a budget
  • understanding how many calls you make and much mobile data you need
  • finding a carrier with good coverage where you live, work and travel to regularly

Looking at old phone bills will help you assess your usage. Asking friends and family about their experience with different networks will be the best way to figure out which provider covers your area best.

With this information you are ready to filter down the thousands of mobile phone plans available to a manageable list of real considerations. The WhistleOut comparison engine will help you dig into your shortlist to be sure that the plans you are looking at come with all of the features you need at a price that you think is fair.

Do you need a new phone?

Smartphones have quickly become an important part of a modern life. Like a computer in your pocket, a smartphone gives you access to the internet, apps, instant messaging and lots more.

Whether you're after a premium new Apple iPhone or Samsung Galaxy, or budget-priced models from Huawei and Alcatel, we can show you how to match this with your usage and data needs on a single line or for your whole family.

To help you choose, we've got comprehensive mobile phone reviews and ratings. We put all new phones through their paces, testing screen quality, camera performance, battery life and more.

We also pull in reviews from other experts from around the world to help find the right phone.

If there's a carrier exclusive phone, our technology also includes phone substitution where it can automatically insert a 'closest match' handset into search results for mobile providers who don't stock the exact model you are searching for.

What is a SIM Only phone plan?

Sim Only phone plans is a mobile phone service sold without a new phone handset, and usually without a long term contract. The provider gives you a SIM card to put into a phone you currently own which gives you access to their network and services.

SIM Only phone plans are becoming increasingly popular because of the flexibility you get from not being locked into a contract. With SIM Only, you are free to move to a different service provider any time you like.

These plans are also extremely affordable. Without an expensive phone to pay for, the monthly cost of a SIM Only service can be half as much as a traditional phone plan, or less.

Why choose a SIM Only phone plan?

The major advantages of SIM Only plans include:

  • No contracts or long-term commitments
  • Save on the monthly cost of a new phone
  • Get many of the same benefits of a phone plan
  • Upgrade to the latest plans when they come out

What is the difference between Prepaid and Postpaid?

There are a few important differences to consider when looking at Prepaid and Postpaid phone plans. With Postpaid plans, you are sent a bill at the end of the month which includes the monthly access fee plus any charges for usage on top of your standard inclusions.

With Prepaid plans, you need to recharge your account at the beginning of the month, and then again if you use up all of the included credit. You are protected from excess usage charges as your access to specific services will stop when you reach your limits.

Why choose Postpaid?

  • Convenience of automatic renewals
  • Same features and extras as with phone plans
  • No contracts
  • Keep your phone number when you switch

Why choose Prepaid?

  • No excess usage charges - only pay for what you use
  • No long term commitments
  • Keep your existing phone number
  • Great for kids and teens

Do you need a cheap phone plan?

You might be surprised to know how much money you can save on your phone bill each month. Phone plans can include numerous extra features, but you will save money by not paying for features you don’t use. Consider the following to see whether you are currently on the right plan.

Our best tip is to give the little guys a shot. There may be comfort in dealing with the major providers, but it is the smaller telcos that have the best deals. These companies share the major networks, so you don't miss out on coverage or speed, and some have local call centres offering great customer support.

Also, choose no contract plans and keep an eye out for a bargain. Phone plans change all the time and you can move your phone number to whichever provider you like. When you spot a great deal, jump on it!

Do you really need these?

  • How much data do you actually use each month?
  • Do you make international phone calls?
  • Is overseas roaming important to you?
  • Will you make use of a data sharing feature?
  • Do you need a new phone or is your old one working fine?
