Every timestamp in your Simbase dashboard, data sessions, SIM events, SMS logs, usage history, is shown in your account's timezone. By default this is set automatically when you sign up, based on the IP address you signed up from. This article covers how to change it and what it affects.
Open the dashboard.
Go to Settings → Personal Details.
Select the timezone you want from the list.
Save.
The new timezone applies immediately, no waiting period and no need to sign out and back in.

Changing your account timezone updates how timestamps are displayed across the dashboard, including:
Data session start and end times
SIM registration and status-change events
SMS send/receive logs
Usage history shown in Data usage and overages
Scheduled behaviour that's defined in terms of time of day, for example Auto-disable, which runs on a UTC window regardless of your account timezone, but any dashboard timestamps you compare it against will reflect your new setting
Changing the timezone doesn't change when anything actually happened, it changes how those times are displayed to you. Underlying records and billing periods aren't affected.
Your account was created from an office, but your team or fleet operates in a different timezone, and you'd rather read dashboard timestamps in local time.
You're troubleshooting an issue with a partner or operator who reports times in a specific timezone, and want to match it temporarily.
No, billing currency is separate and permanent (see Create a Simbase account). Timezone only affects how timestamps are displayed.
Yes, unlike billing currency, the timezone setting can be changed as often as you like.
Auto-disable runs on a fixed UTC schedule regardless of your account timezone. Changing your account timezone changes how that event's timestamp is displayed in your dashboard, not when it actually runs.
Displayed timestamps for historical events update to the new timezone immediately. The underlying event times themselves haven't changed, only the timezone used to display them.
