Migrants from Africa and the Middle-East are opting to trek through the Balkans with the use of GPS in order to avoid both traffickers and the perilous Mediterranean passage.
However whilst GPS navigation has helped many migrants forego the use of traffickers; it is unlikely that smugglers will be completely replaced. There is a growing fear among migrants that GPS will notify border control authorities to their location. GPS only receives satellite signals and does not send.
On May 25 2015 Hungarian Police detained 379 migrants who were then sent back to Serbia. Many of those arrested are believed to repeat the process again.
