Hi to the US.

Your iPhones will work on 2G and 3G and not 4G/UMTS as i've said. This gives you a lot of choices. Aldi on Eplus is one of them. Eplus was bought by Telefónica who owns O2. On 3G they have now free national roaming and you often have two networks available. On the countryside, in remote villages there are still some spots without 3G coverage. But this can happen on any network, while 2G is available nationwide. 3G is normally stable enough for VoIP calls, but there is free WiFi now in many places like McDonalds or hotels too.

Nano SIM cards are a bit tricky, as they are not so widespread available with the cheaper providers. You'll easily get them at the big operator's stores. But with Aldi, you only get hybrid mini/micro SIMs and nano by request through mail. Having a template, you can cut it to size. It uses the same chip, but only a smaller frame around it. Small "Handy" (= cell phone) stores can do the cutting for a small fee too.

Your Huawei E5330 works perfect here on 2G and 3G.When you have used up your data allowance, you'll be throttled in speed, cut off or surf on the expensive default rate. That depends on the provider. Some providers like Aldi let you buy add-ons to upsize or refill your data volume ahead of time. Needless to say, that you are more flexible with these offers. This is explained in detail in the Germany section.

Have a nice trip.
