Yes. There are several Internet service providers in Korea, so that one
should have little trouble accessing multitude of Internet services, let
alone e-mail. See Subject 32) for more details on commercial Internet
service providers in Korea.
For just mail exchange, having an account on Nowcom,HiTel or Chollian
MagicCall, would suffice as Nowcom,HiTel, and Chollian MagicCall(formerly
Chollian) offer mail relay service to their users. You may send e-mail to
your friend/family on HiTel/Magicall/Nowcom by directing it to
[username|usernumber]@nownuri.nowcom.co.kr(or username@chollian.dacom.co.kr,
username@mail.hitel.net). User number is to be used when sending e-mail to a
Nowcom user with Hangul user name. Two new on-line services in Korea, UniTel
by Samsung Data System and KOTIS-Online by Korea Foreign Trade Association
(currently - during pilot test-, both are free of charge) are reported to
offer Internet-mail relay, too.
For the most economically-minded, there's a still cheaper way.(It is free
except that one has to pay phone charge.) The party without Internet link
may connect to KIDS with dial up ( modem number: 02-526-6487~93 2400bps and
8bit/parity none,KSC 5601) and log onto it as 'guest' to get a new account.
If new account is not given to new comers, which appears to be the case due
to lack of capacity of KIDS host to accomodate more users, one can route out
to ARA BBS from KIDS and get accounts there and correspond electronically on
ARA. The party with Internet link doesn't have to connect to KIDS first to
reach ARA, but can directly connect to ARA. See Subject 9) for Internet BBS'
in Korea. CBUBBS also allows dial-up connection(modem numbers: 0431-61-2897
or 0431-61-3125 in Korea) and can be also used for e-mail exchange with your
family and friends without Internet connection.
A few internet services (fashioned after Hotmail) have popped up in Korea.
