If you are constantly hitting your iPhone data limit, the cheapest fix is not changing your habits — it is switching to the right unlimited cellular data plan. In 2026, unlimited iPhone data plans start at around $35/month per line on a family plan, which is often cheaper than a single month of overage charges on a limited plan.

💡
How to switch iPhone data plans without losing your number
Before switching carriers, request a PAC code (UK/IE), port-out PIN (US) or account number (AU/CA) from your current provider. This lets you keep your existing number when you move to a new unlimited iPhone data plan. The switch typically takes 24–48 hours and your service stays active throughout.
Common questions
iPhone data plan FAQ
Is unlimited iPhone data actually unlimited? +
Most unlimited iPhone data plans include a “premium data” threshold — typically 50–100GB — after which speeds may be slowed during network congestion. However, your data is never cut off entirely. In practice, very few users experience throttling unless they are in a congested urban area during peak hours. T-Mobile, Three Ireland and Telstra are consistently rated as having the least throttling on their unlimited iPhone plans.
Which carrier has the best iPhone 5G coverage? +
In the US, T-Mobile has the most widespread 5G coverage for iPhone users, reaching both urban and rural areas. Verizon’s 5G Ultra Wideband is the fastest but limited to dense urban areas. AT&T 5G+ sits between the two. In Australia, Telstra leads on 5G coverage. In Ireland, Three and Eir have the most extensive 5G deployments in major cities. In Canada, Rogers leads for 5G coverage in urban markets.
Can I use my iPhone data plan when travelling internationally? +
It depends on your plan. EU regulations mean all Irish carrier plans automatically include EU roaming at domestic rates — making Eir and Three IE exceptional value for European travel. US carriers typically charge a daily roaming fee (around $10/day) for international data. Australian and Canadian carriers offer roaming day passes or destination-specific add-ons. Always check your plan’s international data policy before travelling.
How do I switch to a cheaper iPhone unlimited data plan? +
The process is straightforward: choose your new plan, sign up online, and request a number transfer from your existing carrier. In the US, you will need your account number and PIN. In Ireland, request a PAC code. In Australia, ask for an account number. In Canada, request a port-out PIN. Most carriers will process the switch within 24 hours while keeping your number active throughout the transfer.
