Can I apply for a phone or broadband modem online?
Yes, Three Mobile offers a service where you can apply to purchase a phone or a broadband modem over the internet. This is a fast and secure way of beginning a relationship with Three as your network provider. Orders placed before 4pm may be dispatched or dealt with by the 3 mobile customer service team the same day, although there is always the possibility that you may need to provide the company with additional information before you are approved for the product that you want.
In these cases, a service representative may contact you using the contact information you provide at the time of application. You may also wish to keep an eye on your email account as you might also be approached via email.
I placed an order online with Three, what happens next?
There are a number of possible outcomes once you’ve placed your phone or broadband order. If you meet Three’s criteria then you may be approved and your order will be dispatched to you via delivery. It is however possible that you’ll need to provide further information, a deposit, or payment over the phone to secure your order.
The deposit may then be reimbursed to you after you’ve received the sixth bill in your contractual commitment, although this of course is subject to terms and conditions. Contact 3 Mobile customer services to learn more.
Can I keep my 3 phone number if I’m switching provider?
Yes, it’s possible nowadays to keep your number when switching providers, and Three mobile offers this service. This makes it very convenient to keep your mobile phone number while having access to all the perks of a new provider and package.
In order to keep your new number you just need to receive your new SIM, or your new device and then get in contact with Three mobile either online or over the phone.
Once you’ve provided your information then Three will undertake the process of transferring your number from your old network to your new SIM or device, meaning it’s a very simple process to keep your old number. This saves time and effort as you don’t have to give out your new number or update your existing contacts, something that is always difficult when upgrading or changing your phone.
Bear in mind that the process of changing or transferring your old number can take up to 24 hours to complete, so make alternate arrangements for being contacted during that time if necessary. If you are still having difficulties call the 3 contact number on this page.
I want to order online, can I have free delivery from Three mobile, and how does my order get delivered?
Firstly, you may be eligible to receive free shipping when you order from Three mobile as long as you live in the UK or ROI. Normally when completing a purchase you will give your home address or current address, and then your order will be dispatched to this address by a courier or delivery service.
You can also have the option of having the product delivered to a local 3Store, a service that Three call ‘click and collect’. This may make life easier if you live in a complex place for delivery or if you aren’t entirely sure when you’ll be home and you need to sign for the package.
Delivery periods usually depend on what the product is you’ve ordered and also any other external factors. It might be that there is a delay in your order but if this is the case you may be contacted by Three either on the phone or email to update you on the situation.
You may also wish to call the Three Mobile contact number to find out what your current order status is.
For mobile phones and broadband modems delivery may often be next working day, so there is minimal delay in receiving your item.
The cut off time according to Three is 4pm, and orders received after this point may be delivered in two working days. You may be asked to sign for these when they are delivered by a courier.
Other products including dongles may be delivered by standard shipping and won’t require a signature on delivery. Make sure when you get in contact with Three about a product you’ve ordered or delivery that you have your order reference number and any other relevant details on hand to speed up communication times and ensure you give the right information.
How much data should I get on my phone plan with Three?
You should consider carefully before signing up to a plan how much data accommodates your needs comfortably to avoid extra charges and also have the services that you require. Often, people may find that Three’s unlimited data plan is the most suitable if they often use their data to surf the web, download content, or stay in touch using social media or email. For reference, Three state that 250MB of data is equivalent to downloading one four minute video, or 2.5 hours of using the internet in a browser.
If your data use habits go above this, then you may want to use Three’s ‘All-You-Can-Eat’ data package which allows you unlimited use of data. If you only use your mobile for data occasionally, perhaps you are better off with 250MB. Contacting the Three number above is another way to find out the best data plan that suits your needs and to see what they have available.
Should I buy a Pay As You Go phone or a contract phone on Three mobile?
This is a complicated question and whether you should get a PAYG phone or a contract phone is something that really comes down to you. However, there are a few things that you may want to consider before signing up with Three.
Firstly, how often you use your phone may affect which package you go for. If you aren’t too keen on using a phone and tend to just send the occasional text message or make a quick call, then perhaps Pay As You Go offers you the basic services that you need.
Nowadays though, contracts are much more affordable than they used to be, especially if you don’t opt for one of the more premium and high-end handsets. This means that you may also find a contract to be reasonable and in-keeping with your needs while not being more expensive than a PAYG phone.
However, if you prefer the no-commitment style of PAYG, you might want to stick with this more traditional Three package. As always you can call the Three phone number on this page to speak with a customer service specialist.
What does it mean if my phone is locked?
Mobile phones are often paid for in part by the mobile phone network, and so this can be a large part of a mobile phone company’s expenses aside from the contract. For that reason, companies like Three will often ‘lock’ a phone which means you can’t use it with the SIM card from a different network provider.
While it’s now common practice for many people to get their phones unlocked, this can technically be seen as breaking the contract you have with your mobile phone provider, so is not a recommended way of doing things.
Phones may also not be as functional if you are not using the network settings that the phone was designed for.
If I switch to Three mobile from my old network can I keep my number?
Yes, you may be able to keep your old phone number, as now it is required for mobile network carriers to allow their customers to keep their mobile phone number if they switch to another network.
To do this, normally the most important thing that you do is receive a PAC code from your old network provider, which is valid for up to a calendar month.
You will however have to find out more information from Three mobile including their detailed policy. You may wish to do this by getting in touch with the company directly over the phone by calling the 3 number listed on this page.
Do I need insurance for my Three phone?
This is entirely up to you, but if you have a very high end model then you may wish to purchase insurance to cover you in case of it being stolen, damaged, or left somewhere or lost. Otherwise, if the worst should happen and you lose or break your phone you may need to pay a large amount of money to cover it and get a new one.
Insurance can add an expense to your phone bill, so it’s worth discussing the cost of insurance and insurance policies available with Three if you think you need insurance.
Will the price of the phone advertised on the website have an additional cost like value added tax?
No, prices are listed on the Three website including taxes and fees like Value Added Tax, so you needn’t worry that the price will be higher, it will be exactly as advertised.
I’d like to make sure that I don’t overspend on my contract, is there any way I can do that?
It is possible to put a spending limit on your contract phone with Three mobile, meaning that your phone will be disabled from using any additional services like text messaging, calling, or data, once you’ve used up your allowance for the month.
Bear in mind that while this might be a suitable thing to do if you’re paying the bill for someone else like a child or family member, you can be caught short in a situation where you need to use your phone and do not want it to be cut off, so it’s worth thinking carefully about whether a cap is the right way to go.
To put a cap on your Three mobile you may wish to call Three and discuss how to do so with their customer service agents.
It’s also worth noting that the network states that they can’t be 100% sure that the cap will always be effective. It may be the case that there is a problem with the network or there are repairs being done, or if you are roaming (using your phone in a different country) it may not be possbile to the cap to take effect.
In addition, some telephone numbers are not covered by this spending limit, and you can still be charged extra fees if you are calling premium lines.
Does Three have good network coverage in my hometown/where I live?
It’s not always easy to say whether you will have great coverage or not with any mobile phone network. However, Three mobile do have a service called a coverage checker which uses your location based on a postcode to judge what level of cover you will have in the area that you live in.
While it’s just an approximate guide, it should give you some idea of whether you will get good coverage or not.
If you discover that you do not have good coverage or are generally unsatisfied with your purchase, Three mobile may be willing to accept a return up to two weeks from the date of buying as long as you have all your original documentation and the handset is in no way damaged or broken.
To find out more about whether this is possible you should contact Three directly.
I want to buy a refurbished phone, but what is it exactly? Why is it cheaper?
Refurbished phones are the models that aren’t exactly brand new, but they were returned to Three within two weeks of being purchased by a customer. This means that they are almost new, but have been owned by someone else previously. Three guarantee that they work just like a new handset.
As part of Three’s guarantee, if you purchase a refurbished phone then you still get an entire year in warranty, and you can also take the phone back to three and return it within the standard window of two weeks (14 days) from the date of purchase.
This means that purchasing a refurbished handset can be a great and effective way of picking up an almost completely new phone at a price cheaper than retail.
I’ve just bought a BlackBerry but I don’t know if my tariff includes things like BlackBerry Messenger, how can I find out?
If you’ve bought a BlackBerry you’ll be pleased to know that your tariff includes standard BlackBerry services, so you will be able to use things like BlackBerry Messenger, Email services, internet and of course the BlackBerry app store.
I’m not sure how much data I should get on my tariff, how can I find out?
It’s a tough question to answer. You should know that roughly speaking, 250 MB of data can allow you to use the internet for around two and a half hours, depending on what you’re doing. Things like downloading videos, especially videos in HD, books, files, or sending multimedia messages over data can quickly add up.
If you don’t tend to use much data, but are really more interested just in sending text messages or making phone calls, then perhaps you can get by with a little data only.
If you’re a medium user then you may wish to consider up to a gigabyte, and if you don’t want to be hassled by worrying about data and whether you’ll run out or go over your allowance, you can always sign up for an unlimited data package with Three mobile. If you wish to find out more about which one is suitable for you then perhaps the best method would be to talk to a customer service adviser at Three.
What does Three mean when they say All-You-Can-Eat data?
When Three talk about their All-You-Can-Eat data plan, what they actually mean is that you have unlimited data and can therefore use as much as you want, whether it be downloading media, surfing the internet, watching YouTube videos or social media, and you will not receive any additional charges or fees when you pay your phone bill.
It’s even possible to sign up for one of Three’s special plans, the One Plan, which allows you to use your laptop to ‘tether’ to your phone. This means you can use the internet from your phone to access websites and email on your laptop, which is a convenient plan if you travel frequently in areas that don’t have access to WiFi.
