## Article

<p>You can top up a Vodafone Pay as you go account in three ways: call or text 2345 for free, or top up online at vodafone.co.uk. All three methods are free to use from a Vodafone Pay as you go mobile. If you have a brand new SIM, you will need to top up at least £5 to activate it.</p>

<h2>How do I top up by calling 2345?</h2>

<p>Call <strong>2345</strong> free from the Vodafone Pay as you go phone you want to top up. Follow the automated prompts, enter your payment card details, and confirm the amount. The credit appears on your account immediately.</p>

<p>If you are setting up a new SIM for the first time, call <strong>18829</strong> instead. That number handles initial registration and your first top-up in one call, also free from a Vodafone Pay as you go mobile.</p>

<h2>How do I top up by text to 2345?</h2>

<p>Send a text to <strong>2345</strong> with the message: <strong>TOPUP</strong> followed by the amount you want to add, then the last four digits of your payment card. For example: <code>TOPUP 10 1234</code>. Vodafone processes the payment and credits your account without you needing to call or log in anywhere.</p>

<h2>How do I top up online?</h2>

<p>Go to vodafone.co.uk and use the Pay as you go top-up form. You can top up your own number or add credit to a family member's or friend's account, which makes this the most flexible option. You will need the mobile number you are topping up and a valid payment card.</p>

<p>One restriction applies to new SIM cards: Vodafone requires you to be connected to WiFi when completing your first top-up online. Make sure WiFi is on before you start.</p>

<h2>What is the minimum top-up amount for a new SIM?</h2>

<p>According to Vodafone UK's official support page, "to activate your SIM card, you'll need to top up a minimum of £5 or buy a Big Value Bundle." If you top up less than £5 on a new SIM, the activation will not complete.</p>

<p>Once the SIM is active, there is no stated minimum for subsequent top-ups, though the Vodafone Pay as you go 1 plan charges £2 for each day you actually use your phone, so keeping a reasonable balance avoids your credit running out mid-day.</p>

<h2>Which accounts cannot use these top-up methods?</h2>

<p>Vodafone is clear on this point: "Top-up isn't applicable for Pay as you go Plus and VOXI accounts." If you are on either of those plans, the 2345 method and the standard online top-up form do not apply to you. Check your account type in the My Vodafone app if you are unsure which plan you are on.</p>
