How to Switch and Keep Your Number

How do I switch my SIM provider and keep my number?

Switching your SIM provider while keeping your current number is a straightforward process. First, request a PAC (Porting Authorisation Code) from your current pay monthly sim network. Then, provide the PAC code to your new provider, who will handle the transfer process for you. This process is known as "porting" your number, and it ensures that you can keep your existing mobile phone number even when switching to a new network provider.

What is a PAC code and how do I obtain it?

A PAC code is a unique code that allows you to transfer your mobile number from one provider to another. To obtain a PAC code, simply contact your current provider and request one. You can usually do this by texting "PAC" to 65075 from your mobile phone, or by contacting your provider's customer service team. Once you have your PAC code, you can provide it to your new network provider to initiate the number transfer process.

How do I transfer my number to a new SIM provider?

To transfer your number to a new SIM provider, give the PAC code you obtained from your current provider to your new provider. They will take care of the transfer process, which usually takes about one working day. During this time, you may experience a brief period of downtime as your number is transferred to the new network. However, once the process is complete, you'll be able to use your new SIM card with your existing mobile phone number.

Understanding 30-Day SIM Only Deals

How does a 30-day SIM only deal compare to 12-month and 24-month SIM deals?

30-day SIM only deals offer greater flexibility compared to 12-month and 24-month contracts, as you can change or cancel your plan each month. However, the monthly cost may be slightly higher than longer contracts. With a 12-month or 24-month SIM deal, you'll typically pay a lower monthly fee and may receive additional benefits like a new phone or extra data allowances. However, you'll be locked into the contract for the full term, which means you won't have the same flexibility to switch plans or providers as you would with a 30-day deal.

How do 30-day rolling contracts work?

30-day rolling contracts, also known as 30-day SIM contracts, automatically renew every 30 days unless you decide to cancel or change your plan. This gives you control over your mobile plan, allowing you to adjust it based on your needs or take advantage of new offers without any long-term commitment. With a rolling contract, you'll pay on a monthly basis for your airtime plan, which includes your data, minutes, and texts allowances. You can usually change your plan or cancel at any time without incurring any extra costs or termination fees.

What are the renewal and cancellation policies for 30-day SIM deals?

Most 30-day SIM deals automatically renew every 30 days unless you cancel before your renewal date. To cancel, simply contact your provider, and they will guide you through the process. Some providers may require you to give a certain amount of notice before cancelling, so be sure to check the full terms and conditions of your specific deal. If you want to change your plan, you can usually do so at any time by contacting your provider or logging into your online account.

Are there any drawbacks to 30-day SIM only deals?

While 30-day SIM only deals offer many benefits, there are some potential drawbacks to consider. For example, the monthly cost may be slightly higher than longer contracts, as providers often offer discounts for customers who commit to a 12-month or 24-month term. Additionally, you'll need to provide your own mobile phone or device, as most 30-day deals don't include a phone or tablet. Finally, some providers may require a credit check for certain plans, even if you're only signing up for a 30-day deal.

How do 30-day SIM deals offer flexibility and minimal credit checks?

This means you can easily switch to a new plan or provider if your needs change or you find a better deal elsewhere.

Special Features and Add-Ons

What special features do 30-day SIM plans offer?

Many 30-day SIM plans come with special features like inclusive roaming in the EU and beyond, data rollover, tethering, and data-free social messaging on popular apps. With inclusive roaming, you can use your UK allowances while traveling abroad without incurring any extra charges. Data rollover allows you to carry over any unused data from one month to the next, so you never lose what you've paid for. Tethering lets you share your mobile data with other devices, like laptops or tablets, while data-free messaging means you can chat on apps like WhatsApp or Facebook Messenger without using up your data allowance.

How does data rollover work with 30-day SIM plans?

Data rollover is a feature that allows you to carry over any unused data from one month to the next, so you can use it in the following month without having to pay extra. For example, if you have a 30-day SIM plan with 10GB of data and only use 8GB in one month, the remaining 2GB will be added to your allowance for the next month. This means you'll have 12GB of data to use in the following month, without having to pay any additional charges. Data rollover is a great way to make sure you're getting the most value out of your 30-day SIM plan, especially if your data usage varies from month to month.

Can I use tethering with a 30-day SIM plan?

Most 30-day SIM plans allow tethering, which means you can use your mobile data allowance to create a Wi-Fi hotspot for other devices, like laptops, tablets, or gaming consoles. This is a great feature if you need to get online while you're on the go, or if you want to share your mobile data with family or friends. However, it's important to keep in mind that tethering can use up your data allowance quickly, so you may want to choose a plan with a higher data limit if you plan to use tethering regularly. Additionally, some providers may have restrictions on tethering, so be sure to check the full terms and conditions of your specific plan before you start using this feature.

Can I get a 30-day SIM deal with a new device or handset?

While most 30-day SIM deals are designed for customers who already have a device, some providers may offer the option to purchase a new phone or tablet alongside a 30-day SIM plan. These deals typically require you to pay for the device outright or through a separate monthly payment plan, rather than including it as part of your 30-day SIM contract. Alternatively, you may be able to purchase a new device on a pay monthly contract with a longer commitment (e.g. 12 or 24 months) and then switch to a 30-day SIM only deal once that contract is finished. Keep in mind that the selection of devices available with 30-day SIM deals may be more limited than with longer contracts, and you may need to check for network compatibility if you're bringing your own unlocked device (e.g. an iPhone or Android smartphone).

How do I switch from a pay monthly contract to a 30-day SIM deal?

If you're currently on a pay monthly contract with a handset included and you want to switch to a 30-day SIM deal, you'll need to wait until your contract is finished or pay an early termination fee to end it early. Once your contract is up, you can request a STAC (Service Termination Authorisation Code) from your current provider, which will allow you to keep your number when you switch to a new network.

When you're ready to switch, choose a 30-day SIM deal that meets your needs and sign up online or in-store. You may need to provide some personal information and pass a credit check, especially if you're signing up for a plan with a high data allowance or premium features. Your new provider will then send you a physical SIM card or eSIM, which you can activate online or by following the instructions provided.

What are data-free social messaging options with 30-day SIM plans?

Some 30-day SIM plans offer data-free messaging on popular apps like WhatsApp, Facebook Messenger, and Twitter, which means you can send messages, photos, and videos without using up your data allowance. This is a great feature if you're a heavy user of social media or messaging apps, as it can help you stay connected with friends and family without having to worry about running out of data. However, it's important to note that data-free messaging usually only applies to the messaging features of these apps, and not to other features like voice or video calling, which will still use up your data allowance. Additionally, some providers may have limits on data-free messaging, so be sure to check the full terms and conditions of your specific plan before you start using this feature.

Choosing the Best 30-Day SIM Only Deal

How do I choose the best 30-day SIM only deal?

To choose the best 30-day SIM only deal, consider your data needs, set a budget, compare offers from different providers, and read the fine print to understand any additional costs or limitations. Think about how much data you typically use each month for things like browsing, streaming, and social media, and look for plans that offer enough data to meet your needs. Set a realistic budget based on what you can afford to pay each month, and don't forget to factor in any additional costs like out-of-bundle charges or international roaming fees. Use comparison websites or check directly with providers to see what deals are available, and be sure to read the full terms and conditions before you sign up.

What factors should I consider when assessing my data needs and budget?

When assessing your data needs, think about how you typically use your mobile phone each month. Do you mostly use it for basic tasks like checking email and browsing social media, or do you stream a lot of video content or use data-heavy apps like gaming or video calling? Look at your previous bills or use a data usage tracker to get an idea of how much data you typically use each month, and choose a plan that offers enough data to meet your needs. When setting your budget, consider how much you can afford to spend on your mobile plan each month, and don't forget to factor in any additional costs like device payments, international roaming fees, or premium services. It's also a good idea to compare prices from different providers to make sure you're getting the best deal for your money.

How can I compare 30-day SIM offers from various UK networks?

You can compare 30-day SIM offers by using comparison websites like Free Price Compare, which allow you to easily see what deals are available from different providers. Simply enter your postcode, select the type of plan you're looking for (e.g. 30-day SIM only), and choose the amount of data, minutes, and texts you need. The website will then show you a list of available deals, along with key information like price, contract length, and any special offers or discounts. You can also check directly with providers by visiting their websites or contacting their customer service teams to see what deals they have available. Be sure to compare not just the price, but also the network coverage, data speeds, and any additional features or perks that come with each plan.

Managing Your 30-Day SIM Plan

What should I do after my 30-day SIM plan period ends?

After your 30-day SIM plan period ends, you have a few options. You can choose to continue with the same plan for another 30 days, either by letting it automatically renew or by manually renewing it yourself. Alternatively, you can switch to a different plan from the same provider, either by upgrading or downgrading your allowances depending on your needs. If you're not happy with your current provider, you can also choose to switch to a different network entirely by getting a PAC code and transferring your number to a new provider. Whatever you decide, be sure to check your account balance and make sure you have enough credit or funds to cover your next month's plan.

Do I need to top up my 30-day SIM plan every month?

Most 30-day SIM plans do not require a manual top-up every month, as they automatically renew at the end of each 30-day period. This means that as long as you have enough credit or a valid payment method on file, your plan will continue to renew automatically each month without you having to do anything. However, some providers may require you to manually top up your account each month, even if you have a recurring plan. This is more common with pay-as-you-go plans, where you need to add credit to your account in order to use your allowances. Be sure to check the terms and conditions of your specific plan to see how it works, and set up a direct debit or recurring payment if possible to ensure you never miss a payment.

How do I cancel my 30-day SIM plan and choose a new offer?

If you want to cancel your 30-day SIM plan and switch to a new offer, either from the same provider or a different network, the process is relatively simple. First, check the terms and conditions of your current plan to see if there are any specific cancellation requirements, such as giving a certain amount of notice or paying a cancellation fee. Once you've met any necessary requirements, contact your current provider to let them know you want to cancel your plan. They'll guide you through the process and let you know if there are any final charges or steps you need to take.

If you're switching to a new provider, you'll also need to request a PAC code from your current provider. This code allows you to transfer your existing phone number to your new provider, so you don't have to worry about updating your contact information with everyone. Once you have your PAC code, sign up for your new plan with your chosen provider and give them the PAC code when prompted. They'll handle the transfer process for you, and your new plan should be active within a day or two.

If you're staying with the same provider but switching to a new plan, you can usually do this online or by contacting customer service. Simply choose the new plan you want and follow the prompts to switch over. Your new plan should be active immediately, and any unused allowances from your old plan will typically carry over to the new one.
