Hi Lizzie,
Do you still have an active Fonic SIM card or would you need to buy a new SIM card anyway? In the latter case, I would recommend buying an Aldi Talk SIM card sold at Aldi supermarkets instead which offers a number of advantages over Fonic/Lidl:
- Aldi does not verify your - mandatory German - registration address by sending out letters, so there are no hurdles for visitors to register.
- Further to that Aldi offers a wider range of mostly cheaper data and voice packages and all can be purchased from the prepaid credit on your SIM card. Fonic/Lidl in contrast requires direct debit payments from a German bank account for some of their bundles of minutes and data allowance.
- Lastly Aldi has scraped roaming fees in the whole EU + EEU + Switzerland where you can now call at very reasonable rates and there's also a fairly priced data pack for use outside Germany (120MB valid for 7 days for € 4.99). So Aldi is also quite interesting should you travel to any other European country in the future.
- As of network quality Aldi uses the eplus network which had issues in the past but as they have massively invested in the modernization of their 3G network while all the other operators have been allocating all their resources to the expensive 4G (LTE) roll-out, eplus now often outperforms its competitors when it comes to 3G.
Given that your Galaxy Note does not support 4G (LTE) and since all the other German operators don't allow prepaid subscribers onto their 4G networks, 3G performance is all what counts for you and that's where eplus is definitely competitive.
Best,
