"SIM Only" Must-Know Facts and Tips
|
SIM only means you are not paying for a phoneAll SIM only plans only cover a service which includes data, minutes and/or texts. You don't pay anything with regards to a phone device, as each plan requires you to have an existing phone.
|
|
The known networks are NOT the cheapest in most instancesNew Zealand's recent arrival of Skinny Direct and Warehouse Mobile offer cheaper data and calling bundles than the likes of Spark, Vodafone and 2Degrees. If you're with a big network, you're probably overpaying.
|
|
Most SIM-only deals are for 28 days, 30 days or one monthThis means you've got more flexibility to cancel, upgrade or downgrade the plan you pick. You can switch providers without paying penalties.
|
|
Even though contracts are 30 days, you will probably have a credit check doneWhile this is mostly a formality, if you do have bad credit your application may be declined and you will need to stick to a pay-as-you-go SIM provider. See our credit score and credit reporting guide for more information. Also, if you're already paying off a phone you may be flagged as a higher risk customer.
|
|
Check the promotion and special offer detailsThere is no point signing up to an offer that locks you in for 12 months if the offer pricing or bonus data/minutes only applies for the first 3 months. Check out exactly what you’re paying over the entire contract period.
|
|
Pick a SIM Only plan that offers the allowance you NEEDDon’t overpay for things you don’t need. If you have internet at home and don’t watch TV on your phone, it’s unlikely you’ll need 10GB of data and unlimited minutes.
|
|
You'll need to have an unlocked phoneCheck your phone, as some phones from Telecom, Vodafone, Skinny and 2degrees will be SIM-locked to their networks. You can find out if the phone is locked by putting a SIM from another provider. To unlock your phone, you’ll need an IMEI number - you can find it by dialling *#06# on most phones or look for it on the label in the battery compartment, or on the box the phone came in.
Each provider’s website gives guidance about unlocking a phone, which is free if your phone is out of contract, or around $30 if it’s in a contract. Phones bought from overseas or via Trade Me will specify if they are unlocked or locked, so always buy an unlocked phone to save any hassle and extra costs. |
|
Check the signal strength where you live and workThere is no point picking a provider if it doesn’t work in your lounge or bedroom. These links just need your address to show if you’ll get 3G or 4G
|
|
Switching from a contract to a SIM deal? Tell your current service provider ASAP!Monthly plans usually require a month in advance notice, so as soon as you know you’re leaving the plan, advise your provider. You will have to pay the final month’s bill, so it’s best to buy the new provider’s sim first and organise your new deal to start as your current provider’s billing month finishes, therefore avoiding being stranded and paying twice for two plans at changeover time.
|
|
Keeping your number is easyOnce you have a new provider’s SIM, you can submit a change of number request online via their website. It’s usually processed in one working day and you can call the new provider’s support team if you have any issues.

Complain about your network using the Telecommunications Dispute Resolution (TDR)
Telecommunications Dispute Resolution (TDR) deals with complaints from consumers about any product or service provided by their telecommunications company. As the customer of a New Zealand network, you have the right to make a complaint. It's a free and independent service, but you will need to follow their process to progress a complaint.
Before you complain, you'll need to raise the issue with your network directly via their complaints form or customer service team
The process of complaining with TDR is outlined here. Their helpful FAQs outline what you can expect, and case studies about recent complaints about telecommunication companies in general. The process is impartial, and once a decision is made, Your network will (usually) abide by the ruling should it be in the wrong.

- Once you have done this, you must wait for a response.
- The network will respond, but if you are unable to agree with their response and your complaint becomes deadlocked, after six weeks has passed you can raise a complaint with the TDR.
