Unlimited data against a network that switches carriers for you.
HelloRoam is eSIMRated's Editor's Choice at 4.9/5 overall. Holafly and Alosim tie on app quality, both at 4.4/5, so the decision comes down to how you use data rather than which app you prefer. Holafly sells unlimited plans only, from $19.00 for 5 days across 160 destinations. Alosim sells capped plans from $4.00 for 1 GB across 170 destinations, and its $15.00, 5 GB, 30-day plan works out to $3.00/GB. At that rate, matching Holafly's $54.00 flat month takes about 18 GB of Alosim data, so light and moderate users pay less on Alosim while heavy users cross over to Holafly's side of the line. Alosim's other advantage is technical: multi-carrier fallback that switches networks automatically if the primary signal drops, plus 5G in select markets. Holafly answers with support, 4.6/5 and live chat in 10 languages against Alosim's 4.0/5 and manual top-up only.
