For mobile internet in Bali, install a travel eSIM before departure or purchase a registered local SIM when you arrive. Roaming can work if your home plan covers Indonesia, while pocket Wi-Fi suits groups. Check your phone's compatibility, data needs, and coverage, especially for remote areas.
The easiest way to get around Bali is to use Grab or Gojek for short journeys and hire a private driver for full-day sightseeing. Public buses and tourist shuttles serve selected routes, while ferries connect islands. Scooters suit experienced, licensed riders, and Bali has no passenger trains.
The best things to do in Mexico include visiting Teotihuacán and Chichén Itzá, exploring Mexico City's historic center, swimming in Yucatán cenotes, and tasting Oaxaca's food. Snorkel in Cozumel, watch whales in Baja California Sur, or ride the Copper Canyon railway. Focus your trip on one region.
Cellular data stops working due to a toggled setting, Airplane Mode being on, a weak signal, a reached data limit, or a SIM card issue. Most fixes take under two minutes. Check your settings first, restart your phone, and reset network settings if needed.
iMessage automatically encrypts messages end to end between supported Apple devices, so no extra setting is needed. Blue bubbles identify iMessage, while SMS and MMS lack end-to-end encryption and RCS support varies. For added privacy, use a strong passcode and Advanced Data Protection for iCloud.
APN stands for Access Point Name. It helps your phone establish a mobile data connection through your carrier. Most SIMs and eSIMs configure it automatically, but incorrect settings can leave you with signal and no internet. Check your data line and use only the APN values your provider supplies.
Deleting an eSIM removes its cellular profile, stopping calls, texts, and data on that line without erasing your phone's files or usually canceling your plan or number. Reinstallation depends on your provider, and some plans cannot be recovered. Turn off the eSIM instead if you may need it again.
GSM stands for Global System for Mobile Communications, a 2G standard that helped make SIM cards and international roaming widespread. Today, travelers should check that their phone is unlocked and supports local LTE or 5G bands, carrier requirements, and VoLTE for calls. GSM alone is not enough.
SOS Only on iPhone means your regular cellular network is unavailable, though emergency calls may still work. Check carrier coverage and outages, toggle Airplane Mode, restart your phone, and review SIM or eSIM settings. If you're abroad, verify roaming support and the active mobile data line.
FaceTime is free to use internationally because it uses the internet rather than traditional phone minutes. Calls over Wi-Fi usually avoid mobile data charges, while cellular calls use your data allowance and may incur roaming fees. A travel eSIM can help you manage mobile data costs abroad.
A SIM card stores subscriber identity, network information, & security credentials, while some physical SIMs also hold limited contacts and SMS. Photos, apps, passwords, and most personal data stay on your phone or in the cloud. Understand SIM security, eSIMs, and what happens when you switch cards.
A travel eSIM is the easiest way for most tourists to get mobile internet in Japan, while local SIMs suit longer stays, roaming suits short trips, and pocket Wi-Fi works for groups. Compare costs, data needs, network coverage, and setup tips to stay connected across Japan.
