A dual SIM mobile phone is a big advantage: You can also insert a SIM card of the country abroad besides the usual SIM card.
This can often save a high cost, because the so-called roaming avoid leaves - during particularly data roaming can be expensive otherwise.
What should we know about roaming?
From roaming we speak the way, whenever you use a mobile network with a SIM card that does not originate from the same country. The special thing about it: Often require the card company for the same mobile services that cost within Germany only a few cents or in individual flats are already included, be significantly higher.
Thus, a three-minute call from abroad to Germany via a German SIM card in dual SIM mobile phone (of course any other phone) ever cost 10 €, depending on the country, dortigem Mobile Network and the own card issuer.
Cost of data roaming may explode
Especially tricky: Many are now used by the introduction of Flats that calls or mobile Internet in Germany nothing cost more, at least not on the one-time flat fee per month beyond.
but abroad these flats are not usually, ie who worry a Internetflatrate the dual SIM phone makes this country transmit one megabyte after another, obtained for the same surfing activity abroad a fierce statement. In the press were already often cases in which significantly more than € 10,000 came together because the holiday mood is naturally handled in retrospect the opposite.

But beware: Even for accepting phone calls abroad can result in relatively high costs.Furthermore you should be best informed in its carrier in the tariff conditions. After all: within the EU and certain other European countries (eg Switzerland) the roaming costs were indeed reduced in recent years repeatedly, but here can still spring a surprise or threaten.
