Yup. And that's what dxdydz offered a solution for. It's not perfect, but for regularly crossing the border there's no other way unless you start swapping sims.
The roaming issue is a problem for mobile operators in many places.
It is one thing to have a roaming charge on your bill when you never left the country, it is another when an emergency call is misdirected to the wrong country.
Turning voice roaming off used to be a lot easier than it is today.
As a diver this story of an emergency call gone wrong really hit me:
Actually, no. It is much easier today, the only difference is that the roaming costs (that is, the costs of calls received and originated) have dropped so much in the last 15 years, that nobody cares anymore to control it.
15 years ago, cost of 20-minutes voice call, when in roaming, would bankrupt you. Nowadays even teenagers on holidays do not worry too much.
It's not easier. It's often buried in menus and the GSM codes don't work on all networks. Teenagers don't care because their parents pay the phone bill.
I am with Orange. I pay an additional 4Chf per month on my bill for roaming. Its kept my bills quite low but I wouldn’t use the internet unless i needed (As in, no randomly checking FB, Mail etc..)
My husband is with Swisscom. He has a 100 minute roaming package. This means he has 100 minutes to play with. . . before roaming costs him.
I always use my Irish simcard when I go home but he doesn’t have too. He can make/receive up to 100 minutes of phone calls a month while roaming without it costing anything additional... plus the package include texts & internet.
I live in Saint Louis & spend alot of time in Germany but luckily Swisscom and Orange have quite good coverage over the borders.
