Read their web pages carefully because imho the software is a bit unusual, the queuing system is based on your existing bag's end date, if the first bag runs out of data before its end date your next bag does not auto start until the first bags end date is reached and in the meantime any continued data use counts against any unallocated top up cash you have left at a much more expensive rate. Alternatively to use your new bag immediately in the process of buying the new bag you have to opt for a new starting date, which auto cancels your original bag and you lose any data left in it. Whether you have any credit in your account or not you are also required to top up again within a given time interval (can't remember exactly how long usually about 3 months they send you a reminder email) to maintain the service. Although it looks value you can get caught for expensive data unless you know how to use the system to your best advantage. **Q: Does it come with a tool to open the SIM card slot?** A: No this doesn't come with SIM removal tool as different phones require different SIM removal tools ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great valuy *by M***E on 1 February 2026* Use this in a senior phone as a replacement landline.so much cheaper to run.Super happy 😊 ### ⭐⭐⭐⭐⭐ Multi SIM Card Giffgaff O2 4G. *by P***. on 16 April 2026* Quality product. ### ⭐⭐⭐⭐ Is what it is *by A***R on 3 November 2022* It’s a SIM card simple as that ## Frequently Bought Together - giffgaff O2 4G Multi Sim Card For PAYG - UNLIMITED CALLS, TEXTS & DATA - get £5 BONUS CALL CREDIT with your first Top up!
