Confused about plans - for existing customers

Hi, I've been using IDmobile for a while now, and I'm a bit confused about getting a new plan when my pay as you go expires.

On the site there are regular plans, and special plans 'for existing customers' that seem to be much better value.

But the 'existing customer'plans try to send me a new SIM card if I purchase one.

Is it really most cost efficient to keep getting new SIM cards rather than using the same one? Can anyone help me understand what's going on here? Why can't I just buy these 'existing customer' plans for my current SIM?

Thanks,

Hi @ikinone,

Thank you for getting in touch.

Kindly note that although you are an existing Pay As You Go customer, it is not possible to upgrade directly to a Pay Monthly plan, as our system does not support upgrades from Pay As You Go to Pay Monthly. To move to a Pay Monthly plan, you would need to purchase a new plan, which will include a new SIM card and number.

Pay Monthly customers, however, are able to upgrade their plans without receiving a new SIM card or number, as the upgrade is processed on their existing SIM and number.

Thanks,

Anneline

So what’s the point of the Pay as you go SIMS, if you get a monthly plan that is far less value than a monthly plan on a monthly SIM?

Is the main difference on PAYG that you can also have credit which is used gradually?

Hi @ikinone ,

You’ve got it, the main difference with Pay As You Go (PAYG) is that you top up your SIM with credit and use it gradually for calls, texts, or data, without being tied to a monthly contract. PAYG is flexible and low commitment, but it doesn’t offer the same value or included allowances that Pay Monthly plans provide.

Pay Monthly plans give you larger allowances (minutes, texts, data) for a fixed monthly cost, which is usually better value if you use your phone regularly. However, upgrading from PAYG to Pay Monthly requires a new SIM and number, which is why it seems less straightforward.

So, PAYG is mostly about flexibility, while Pay Monthly is about value for regular usage.

Fantastic! So what’s the easiest way to switch to a monthly SIM? And with a monthly SIM, if a monthly plan expires, how long can I leave it ‘unsubscribed’, before needing to reactivate it?

Thanks,
