Ordered by the published monthly price of an unlimited data SIM, because it is the one plan every publishing seller publishes and the only line that compares cleanly: 30 GB at one seller and 40 GB at another are different products. Sellers whose pages could not be read are listed after them with what the read returned, never with a guess.
What to know before you switch
- eSIM An eSIM is the same plan as a plastic SIM with the card taken out of it: the profile is downloaded to the handset instead of posted.
- PAC codes and switching A PAC code is the seven-character code that moves your number to a new network, and a STAC is the one that closes the account without moving the number.
- Data roaming Roaming stopped being free with the EU and did not stop being sold, so it is now a line on the tariff rather than a right, and the sellers split into three groups: those that include it in the allowance, those that sell it as a daily or weekly pass, and those that say nothing on the page at all.
- Contracts and terms A mobile phone contract in this record means airtime on a term, not a handset paid off monthly, and keeping those two apart is most of the value of comparing them at all.
