AT&T rates in Australia
International Day Pass details, billing cap, and hidden fees.
Day Pass Daily Breakdown
AT&T International Day Pass connects your phone to Telstra, Optus in Australia. You pay $12 every day your device touches the network. Background app syncs, iMessage fallbacks, and incoming MMS all trigger the full daily charge. There is no partial-day billing.
Monthly Billing Cap
AT&T caps Day Pass charges at $120 per billing cycle (10 days of use). After the cap, roaming is included for the rest of the month. A travel eSIM for Australia costs $3.49 total, which is 90%+ less than hitting the cap.
T-Mobile rates in Australia
Free 2G tier, Go5G Plus, and International Pass.
Free 2G Tier Reality
T-Mobile Magenta includes free roaming in Australia at 128 kbps. That is 2G speed. Maps load in 30+ seconds. Photos will not send. Video is completely unusable. Local networks in Australia average 195 Mbps. Your eSIM runs at that full speed, over 1523x faster than T-Mobile's free tier.
Go5G Plus High-Speed Included
Go5G Plus customers get 5GB of free high-speed data per month while roaming in Australia. After 5GB, speeds drop to 256 kbps. This is the best carrier roaming deal among all six carriers tracked here, but it requires T-Mobile's most expensive domestic plan.
International Pass $10/Day Option
T-Mobile raised the International Pass from $5/day to $10/day in 2026. It unlocks LTE speeds on Telstra, Optus. A 7-day trip costs $70 with the pass. A travel eSIM costs $3.49 for the same week.
Verizon rates in Australia
TravelPass, auto-enrollment, and data top-ups.
TravelPass Daily Cost
Verizon TravelPass costs $12/day in Australia. You get 5GB of high-speed data per day. After 5GB, speeds drop to 3G. Charged any day you use service, including one background app sync.
Auto-Enrollment Warning
Verizon auto-enrolls TravelPass on many postpaid lines. Your phone starts incurring charges the moment it connects to a network in Australia. Opt out through the My Verizon app before you depart. Missing this step is the most common source of unexpected roaming bills.
Data Top-Up Costs
After 5GB in a day, Verizon throttles to 3G. There is no option to buy additional high-speed data for that day. Heavy data users hit this cap quickly when streaming maps, uploading photos, or video calling.
Monthly International Plan
Verizon offers a $100/month Monthly International Plan with 20GB of data. For trips longer than 8 days, this beats TravelPass on cost. A travel eSIM still costs $3.49 for the same period.

Data throttling policies by carrier
What happens after you hit the high-speed cap.
AT&T provides 2GB of high-speed data per 24-hour period on International Day Pass. After 2GB, speeds reduce to 128 kbps for the remainder of that period. The 24-hour clock starts when your phone first connects to a foreign network, not at midnight local time. AT&T reduced this cap from 3GB to 2GB in recent plan updates.
T-Mobile Magenta's free international data is permanently capped at 128 kbps. There is no high-speed window. The free data is unlimited in volume but unusable for most modern internet activities. Go5G Plus includes 5GB at full speed, then drops to 256 kbps.
T-Mobile's $10/day International Pass provides 2GB of high-speed data per day. After 2GB, speeds drop to 256 kbps (roughly double the free tier speed). The 2GB counter resets at midnight local time.
Verizon TravelPass provides 5GB of LTE data per day. After 5GB, speeds drop to 3G for the rest of that calendar day. The 5GB counter resets at midnight local time. There is no option to purchase additional high-speed data for that day.
Vodafone applies a 25GB monthly fair use cap on roaming data. Beyond 25GB, Vodafone charges GBP3.13/GB in overage fees rather than throttling speed. This can result in significant unexpected charges for heavy data users.
EE applies a 25GB monthly fair use cap on roaming data. Beyond 25GB, overage charges apply per MB. The cap is shared across all roaming destinations in the same billing period.
Three caps Go Roam data at 12GB per day. After 12GB, data is suspended entirely (not throttled) until the next calendar day. This is the most aggressive cap among all six carriers. Heavy tethering or video streaming can trigger the cap within a few hours.
US carrier roaming analysis for Australia
US carrier roaming in Australia and Oceania follows standard global pricing. AT&T charges $12/day via International Day Pass. Verizon charges $12/day via TravelPass. T-Mobile includes free data at 128 kbps.
Australia averages 195 Mbps on Telstra and Optus. Oceania trips tend to be longer than European trips (10-14 days typical), which makes carrier roaming costs add up faster. AT&T's $120 monthly cap helps for trips exceeding 10 days. Verizon has no monthly cap, so a 14-day trip costs $168.00. A travel eSIM at $3.49 covers the entire trip at a fraction of any carrier's cost.
UK carrier roaming rates for Australia
UK carrier roaming costs increase significantly outside the EU. Vodafone Roam Further charges GBP6.85/day in Australia. EE Roam Further charges GBP5.91/day. Three Go Roam covers Australia at GBP2.75/day, which is the cheapest UK carrier option.
For worldwide destinations including Australia, UK carrier roaming is more expensive than US carrier roaming. Vodafone at GBP6.85/day (approximately $8.50) exceeds both AT&T and Verizon at $12/day. EE at GBP5.91/day (approximately $7.50) is also more expensive than US carriers. Only Three at GBP2.75/day (approximately $3.50) undercuts US carrier pricing, but only in its 71 covered countries.
A travel eSIM at $3.49 for 1GB on Telstra and Optus costs less per day than any UK carrier roaming option for Australia. For UK travelers visiting worldwide destinations, the cost advantage of a travel eSIM is even more pronounced than for EU travel.
