What to compare
Four things that matter
1
Data allowance
Check your typical monthly usage instead of automatically choosing the largest allowance.
2
Promotional period
A low headline price may apply for only part of the contract. Read what happens later.
3
Price changes
Look for provider-published annual increases and the exact dates they take effect.
4
Roaming & speed
Roaming allowances, speed caps and fair-use conditions can materially change the value.
